Opis:
This paper outlines the issue of the conservation protection of archaeological heritage using the example of three sites from the communes of Gniezno and Łubowo entered in the register of monuments. The sites in Moraczewo (site 16), Lednogóra (site 8) and Goślinowo (site 4) are briefly presented. The first part presents international and national legal acts referring to the protection and care of monuments in a historical perspective. Next, operative regulations are presented from the practical side. The paper describes the scope of their execution, executive possibilities for conservation services and the problems of cooperation between administrative units at various levels in the broadly understood system of monument protection. The issue of the value of cultural heritage, still much-debated not only in the conservation but also in the scholarly milieu, is also discussed. The importance and preservation of the relics of the past in contemporary society is best illustrated by the current proceedings to receive the consent for the construction of a lignite opencast mine in Ościsłów. The investment has received wide coverage in the social media, television and the press among others due to the discovery of a megalithic cemetery, thus confirming that the value of heritage cannot be measured only by objective and standardised criteria. The issues of property and finances are considered the main problems in the protection of monuments. The responsibility for the monument lies primarily with the owner and the costs associated with the maintaining and good preservation of the heritage are often very high. This paper therefore emphasises the need for a closer cooperation between conservation services and monument owners or investors. Theoretical and legal considerations lead up to a discussion on the problem of the protection of archaeological heritage in real situations. Examples here include three sites under one of the higher forms of protection, i.e., an entry in the register of monuments, which are under threat from investments. First, the site in Moraczewo may be destroyed by a significant extension of a residential building and the construction of a car workshop. Secondly, Lednogóra is an example of an archaeological site difficult to protect by conservation services due to faulty provisions in the current local spatial development plan that was adopted almost 20 years earlier. Finally, the Goślinowo site is threatened by destruction due to the implementation of the construction of the S5 express road, a strategic investment for this part of the country. The examples discussed illustrate the diversity of activities undertaken by conservation services. However, as the above analysis demonstrates, the complexity of the problems related to the protection of cultural heritage is not limited to the possibility of applying relevant paragraphs. We often face a dilemma as to how much compromise we should make to protect as much of our archaeological heritage as possible.

Opis:
Szkło, wykorzystywane do produkcji przedmiotów, jest jednym z najdelikatniejszych materiałów, który bardzo mocno reaguje na zmianę temperatury i wilgotność. W procesie wydobywania obiektu z gleby i przenoszenia go do niecodziennego otoczenia często może nastąpić gwałtowne zniszczenie znalezisk archeologicznych: zmiana koloru, struktury i kształtu. Szkło odkrywane w czasie badań archeologicznych jest materiałem nietrwałym. Przedmioty szklane, zwłaszcza z okresu średniowiecza, które mają znaczną ilość domieszek, są podatne na zniszczenia. Jeśli proces wypłukiwania jest bardzo zaawansowany i spowodowany korozją, wówczas znalezisko archeologiczne może w ciągu kilku minut zmienić się w pył. Badania wykopaliskowe przeprowadzone w 2018 roku na terenie Narodowego Rezerwatu „Sofia Kijowska” dostarczyły wyroby szklane datowane na XI–XX wiek: kostki starorosyjskiej mozaiki, ułamki smalty, średniowieczne szkło okienne, naczynia apteczne, ułamki szklanej biżuterii i fragmenty naczyń kuchennych (ryc. 2–7). Spośród wszystkich znalezisk konserwacji należało poddać fragmenty silnie skorodowanych starorosyjskich naczyń cienkościennych oraz dwie kostki mozaikowe w kolorze błękitnym, które zostały zniszczone na skutek zdeponowania w środowisku zasadowym. Zabytki te zostały oczyszczone z powierzchniowego zanieczyszczenia za pomocą miękkiej szczotki oraz utrwalone przy użyciu 3–15% roztworu Раraloid B-72 w acetonie. Tę samą metodę konserwacji zastosowano w wypadku butelki aptecznej z XVII–XVIII wieku (ryc. 5–7). Pozostałe wyroby szklane zostały oczyszczone z zanieczyszczeń za pomocą miękkiej szczotki oraz zapakowane w woreczki. Ich konserwacja zostanie przeprowadzona w warunkach laboratoryjnych.

Opis:
Połów ryb był jednym z powszechnych sposobów pozyskiwania pożywienia we wczesnym średniowieczu. Znaczenie tego pokarmu rosło wraz z upowszechnianiem się chrześcijaństwa i wymogiem przestrzegania postów. Stąd także w przypadku mieszkańców Ostrowa Lednickiego rybołówstwo musiało być powszechną i codzienną praktyką zdobywania pożywienia. Dzięki wieloletnim podwodnym badaniom archeologicznym prowadzonym w jeziorze pozyskano zbiór ponad 30 przedmiotów identyfikowanych jako narzędzia związane z rybołówstwem. Natomiast analiza szczątków kostnych znalezionych podczas badań lądowych dała możliwość rekonstrukcji składu gatunkowego ryb i preferencji kulinarnych mieszkańców Ostrowa Lednickiego we wczesnym średniowieczu. Pozwala to, w oparciu o dane z obydwu obszarów badań, rekonstruować ów ważny fragment życia wczesnośredniowiecznych mieszkańców okolic jeziora Lednica, jakim było rybołówstwo.
Fishery was one of the common ways of obtaining food in the early Middle Ages. The importance of this element grew along with the spread of Christianity and the requirement to observe fasts. This way of obtaining food must have been common for the inhabitants of Ostrów Lednicki as well. A collection of more than 30 objects identified as fishing equipment was obtained through years of underwater archaeological research. The analysis of skeletal remains found during land surveys has provided an opportunity to reconstruct the composition of fish species and culinary preferences of the inhabitants of Ostrów Lednicki in the early Middle Ages. By combining these two types of sources, it is possible to reconstruct that part of the life of early medieval people which was made up of fishery.

Opis:
Advanced noninvasive research carried out in “The cradle of the Piasts: archaeological underwater prospections in the area of Lednickie Lake” (“Kolebka Piastów archeologiczne prospekcje podwodne w rejonie Jeziora Lednickiego”) project, provided a new collection of artefacts and archaeological sites. In the first stage of the project an archive research was carried out and it showed that there are 61 archaeological sites of different character and chronology in the close proximity to the lake. In the further part of the project, non-invasive research with the use of a magnetometer, a multibeam sonar and a subbottom profiler were conducted. This stage of the project was possible due to cooperation between the team from the Maritime Institute in Gdańsk, which was conducting hydroacoustic research, and underwater archaeologists. In the course of the survey of bathymetric anomalies between Ledniczka island and the west coast of the lake, construction elements were identified. Therefore, the terrain between an island and the mainland was thoroughly searched in order to verify the object which was found. During the search of the bottom by the divers in the designated place, more horizontal structural elements were identified. Localizing vertically impaled wooden constructions identified as piles, was the key point. These elements confirm that in the described place, there was a third bridge on Lake Lednica. Samples for dendrochronological and radiocarbon dating were collected from the P1, P4, P5 piles and V object. Only the sample from object V was suitable for dendrochronological dating, as it did not contain a sapwood layer. As a result it was possible to determine the date when the tree was cut, i.e. after 1293, hence most probably at the turn of 13/14th centuries [Ważny 2017]. Sample wood from pile 1 was subject to radiocarbon dating and the 1085±30 BP date was obtained. After calibration it can be said that it is 68.2% probable that the analyzed material comes from 900–993 (900–922: 22.3%; 948–993: 45.9%). Whereas it is 95.4% probable that it comes from 894–1016 (894–932: 30.5%; 937–1016: 64.9%) [Goslar 2017]. In conclusion, it can be said that during the research, the relics of the bridge leading from the mainland to Ledniczka island located on the W–E axis were localized. The crossing is located at the narrowest place between an island and the mainland. This is around 100 meters and this is the probable length of the bridge. On the basis of the variety in the degree of wood conservation, as well as diverse shapes of the construction elements, and especially the obtained dates from the radiocarbon and dendrochronological datings, it can be assumed that there are two bridge crossings which date to the 10th century and the turn of the 13th and 14th centuries. During the 2017 research season an interesting discovery was made. After several seasons of underwater works, a new object was localized and identified as bridge relics. It shows the great archaeological potential of Lednica Lake and how the use of new noninvasive methods can lead to spectacular discoveries. The bridge relics were only identified on the surface level, therefore it is difficult to draw far-reaching conclusions. However, dendrochronological dating makes it possible to determine the origins of the bridge to the 13th/14th century. Militaria found near the bridge are also from this period. The C14 date, which estimates the age of one of the piles for the 2nd half of the 10th century, is very interesting. It can indicate that there were two bridges with different chronology. However, in order to confirm this, further excavation works must be conducted.

Opis:
In the 2015 season, the underwater research in Lake Lednica focused on further exploration of two exploration plots of the Poznań bridge — 7 in the XCV area and 5 in the XCIII area and on the opening of a trial trench in the area of Ostrów Lednicki island. During the exploration of plot 5 in the XCIII zone, the wicker object in a radiating out shape was localised. Because of its archaeological value and the need of further exploration, the object was excavated and handed over to the Museum of the First Piasts at Lednica for preservation. The excavated object is probably a trap, a type of fish trap called ‘wiersza’ (a wicker fish trap). During examination of the object and cleaning after excavation, a great number of animal bone remains were collected and analysed. They almost exclusively came from fishes. In the bone material, the remains of several fishes were found: a catfish, eight perches, a pike, the fishes of the Cyprinidae family, including at least two roaches, as well as three remains of a pig. In the case of a catfish and the perches there were elements from all parts of the skeletons, while several bones belonged to two roaches and there was one pike tooth. The latter element was probably included in the assemblage accidentally. The conducted analysis shows that the catfish with SL (standard length) 70–75 cm and the perches, in most cases the large ones with SL=35–45 cm, were trapped in the fish trap. It is, however, not certain whether the roaches caught in the trap or had earlier been caught by predatory fish or fishes found in the trap. It is suspected that a phalanx and two ribs of a young pig, which probably come from the same animal, are the remains of a fishing bait placed in the wicker fish trap. Radiocarbon dating of the organic material which the object was made of indicates that it was placed after the bridge was no longer in use, probably in the late 12th or the early 13th century. For unspecified reasons the described wicker fish trap was not emptied and was left among the relics of the early medieval bridge. The discovery of the remains of the wicker fish trap and the analysis of its contents brought new information about one of the ways of fish harvesting used by the inhabitants of the area of Lake Lednica and its efficiency.

Opis:
In den vergangenen Jahren hat sich das Archäologische Museum Hamburg auf die Untersuchung und wissenschaft liche Neubetrachtung der beiden wichtigsten Befestigungsanlagen im Zentrum von Hamburg konzentriert. Die Ergebnisse der jüngsten Ausgrabungen in der Hammaburg (2005-2006) und der Neuen Burg (2014-2020) trugen maßgeblich zur Neubewertung der frühmittelalterlichen Stadtentwicklung Hamburgs bei. Die annähernd lückenlose Entwicklung der Stadt von den Anfängen als einfache sächsische Befestigungsanlage über die namengebende Hammaburg bis hin zur „Neuen Burg“ als eine der größten Befestigungen Norddeutschlands kann durch die archäologischen Untersuchungen nachgezeichnet werden. Künft ige Forschungen der übrigen Befestigungsanlagen im Stadtgebiet werden sicher weitere wichtige Ergebnisse zur Entwicklung der Region während des Mittelalters liefern.
W ostatnich latach Muzeum Archeologiczne w Hamburgu skoncentrowało swoje prace naukowe na zbadaniu i ponownej analizie dwóch najważniejszych założeń obronnych w centrum Hamburga. Prace wykopaliskowe przeprowadzono w Hammaburg (2005-2006) i Neue Burg (2014-2020), a ich wyniki pozwoliły na ponowną ocenę urbanistycznego rozwoju wczesnośredniowiecznego Hamburga. Dzięki badaniom archeologicznym można prześledzić niemalże nieustanny rozwój miasta, trwający od jego początków jako prostego saksońskiego założenia grodowego, poprzez rozwój Hammaburg, od którego miasto wzięło swoją nazwę, aż po powstanie Neue Burg jako jednego z największych założeń obronnych w północnych Niemczech. Przyszłe badania pozostałych grodów występujących na terenie miasta z pewnością dostarczą kolejnych ważnych materiałów dotyczących rozwoju regionu w okresie średniowiecza.
In recent years, the Archaeological Museum Hamburg has focused on the investigation and scientific re-examination of the two most important fortifications in the centre of Hamburg. The results of the recent excavations at Hammaburg (2005-2006) and Neue Burg (2014-2020) contributed significantly to the re-evaluation of Hamburg’s early medieval urban development. The almost seamless development of the city from its beginnings as a simple Saxon fortification via the Hammaburg, which gave it its name, to the “Neue Burg” as the largest fortification in northern Germany, can be traced through the archaeological investigations. Future research on the other fortifications in the city area will certainly yield further important results on the development of the region during the Middle Ages.

The aim of the paper is to discuss an experiment concerning the (re)construction, structure and use of a Roman glass furnace. In the course of the designing of the experiment, a scheme proposed by Coles was used. e (re)construction was based on three categories of sources: archaeological (a find of a furnace from Hambach Forst), iconographic (olive lamps with depictions of furnaces), as well as earlier experiments of this kind. e feature in question was a two-level cupola furnace. For its construction, specially prepared roofing tiles, sandstone and clay with an admixture of sand and hay were used. Oak and birch wood was used to heat the furnace. Temperature values in the furnace were measured with a pyrometer in four spots. The following conclusions were drawn: it was not possible to achieve the required temperature in the furnace due to a too small opening in the fire-grate and the use of fresh and unseasoned wood. Furthermore, errors were made in the course of the construction of the furnace. These were: an improperly built part of the fire chamber wall and too flat arcs above the openings in the furnace. The validity of these conclusions was checked; the opening in the fire-grate was enlarged; seasoned oak and birch wood was used, and the cracks were fixed and filled up. No accurate temperature measurements were taken in the course of the second "ring. However, in all probability a sufficiently high temperature was achieved, as glass cullet in the furnace melted.

Opis:
Noninvasive surveys and prospections are a new dynamic trend in contemporary archaeology. They represent a trend of multidisciplinary analyses of cultural heritage. Due to limited access to technology, these methods are still not widely used in underwater archaeology, in particular in inland reservoirs. For this reason a team from the Department of Underwater Archaeology of the Institute of Archaeology at Nicolaus Copernicus University in Toruń in cooperation with the Maritime Institute in Gdańsk, the Museum of the First Piasts at Lednica and the Scientific Association of Polish Archaeologists (Warsaw branch), planned and completed a project Kolebka Piastów — archeologiczne prospekcje podwodne w rejonie jeziora Lednickiego in 2017. The project was financed by the Ministry of Culture and National Heritage under the following programme: Cultural heritage, priority: The protection of archaeological monuments. In the course of the project a multibeam probe, a subbottom profiler and a magnetometer were used to conduct surveys. If the conditions and assumptions of the project allowed, a direct underwater verification was conducted. Due to multibeam sonar it is possible to obtain a reliable spatial picture of a lake bottom in high resolution, e.g. 100 or more measurement points for each m2 of the bottom, which enables one to conduct a detailed overview of a surface of the research area and objects lying on it. This method turned out to be the most effective during verification and resulted in the localization of a new medieval bridge in Lednica lake. Using a subbottom sediment profiler is at the moment the only noninvasive method of searching for non-magnetic objects sunk into the bottom. After applying it on a recognized object, such as the Poznań bridge, and after receiving the positive results, it may be assumed — with high probability — that this technology will succeed in the search for other wooden archaeological structures located in subbottom sediments. Magnetometric measurements are the next technology which was used in the researched reservoir. They are indispensable when noninvasive large scale searches of metal objects with magnetic signatures are conducted e.g. the objects made of iron or steel. In the area of Lednica lake several objects with a magnetic signature were localized. In the course of research in Lednica, three types of noninvasive prospections were applied: hydroacoustics (a multibeam probe), seismology (subbottom sediment profiler) and magnetics (Caesium magnetometer). Each of these methods helps to localize other objects and gives very interesting results; however, only after all three have been used is it possible to obtain a precise picture of the bottom of the lake together with anomalies, which to a large extent can have anthropogenic origins. It seems that the future of underwater archaeology is closely related to the described noninvasive surveys. Unfortunately it will be more difficult to achieve in shallow inland reservoirs than in sea waters, where these technologies have already been introduced for some time now.

Opis:
In the introduction, this paper refers to two previous actions aimed at extracting dugout boats from the bottom of Lake Lednica (in 1960 and 1982). The main part of the text presents the third action, carried out in 2016 by underwater archaeologists and students from the Department of Underwater Archaeology, Nicolaus Copernicus University. The paper explains the subsequent stages and procedures of investigations. All the difficulties and complications that arose from the circumstances of the deposition, the raw material from which the boat was made and the size of the object are emphasised. As shown by the 1997 study, the boat is made of wood from the lime tree. The boat is now 930 cm in length and 86 cm in width. The bow looks like a slightly oval pyramid; the stern was formed in the shape of a small overhang and could have been about 1 m longer. The dugout has three bulkheads: the first is the same height as the sides, the second one is shorter than the sides by about 6 cm and the third, formed stepwise (?), starts at the same height as the starboard and keeps this height to the crack, after which it is gradually lowered, going down about 5 cm below the port. The average thickness of the starboard is 5.5 cm, while the port is 4.5 cm thick. The thickness of the bottom at the stern break, ranges from 4 cm to 8.5 cm; in other breaks, it reaches as much as 19 cm. The dugout boat is poorly preserved. It has at least nine transverse cracks and one longitudinal crack ending at the first bulkhead. Part of the damage dated certainly back from the period of the destruction of the bridge; however, a thin layer of sediments covering the side or bulkhead wood did not protect the dugout from the anchors of modern fishing boats. The boat was dated using the C14 method (680 ± 120 BP); calibrated, this points to a very wide range of dates, between 980 and 1454. However, a stratigraphic analysis indicates that the boat fell to the bottom sometime between the period the bridge was completed (964) and the last major repair of the bridge captured by dendrochronological analyses (1023). The first stage of the action consisted in the underwater exploration of the bottom deposits with a water-type ejector. This was used for removing the sediments filling the inside of the boat and those within a belt of a small width on the outside of the sides of the dugout, so that they were clearly visible to a height of approx. 10 cm. The boat was filled with a layer consisting of a large number of strongly compacted chips, which produced a few artefacts: 11 potsherds, five bone fragments and a handle of a wooden cup that was preserved in two fragments. After the whole boat had been cleaned, underwater measurements were taken, which enabled the detailed drawing documentation of the dugout in situ. The second stage consisted in cleaning the area outside the boat with 25–30 cm wide and approx. 40 cm-deep trenches running along both sides of the boat and below them. The sides were cleaned gradually, in 2 m long-fragments, to prevent uncontrolled suction of the boat from the bottom and to reduce the possibility of accidental damage. After completing the exploration of each fragment, separated from the others with natural cracks, the released parts were slipped onto a properly prepared tin ‘trough’, surfaced using a buoyancy balloon and transported close to the shore.In the third stage of the campaign, special frames were prepared for each of the nine elements. After the individual parts had been put on the frames in water, they were brought to the surface with them, secured and transported to the Conservation Laboratory in Toruń. After completing all conservation and reconstruction procedures, the dugout boat will be made available to visitors at the Museum of Polish History in Warsaw.
