    Opis:
    Three objects were studied within a project aimed at investigation of stones used in the Romanesque edifices in the vicinity of Kraków, and continued since 2019. These are the churches in Dziekanowice (21 km SE of Kraków) and in Czchów (58 km SE of Kraków), and a clergy house in Morawica (13 W of the Kraków city centre). The church in Dziekanowice is relatively completely and well preserved, while the only Romanesque remnants of the church in Czchów are those reused in the Gothic church. It is a clergy house in Morawica (a former castle), whose walls contain Romanesque fragments. Two former edifices are built of the Istebna sandstone (Upper Cretaceous-Paleogene), quarried from the local flysch bedrock. Fine-grained, grey-yellowish stone dominates. It is soft and easily workable due to argillaceous binder (matrix). The stone blocks are precisely shaped and well fitted. Romanesque remnants of the clergy house in Morawica are con- structed predominantly of limestone, also of local origin. Only a fragment of the NW wall is built of the Istebna sandstone. This fragment is probably a part of the butress supporting the NW wall. The study shows that stonemasons and builders of that time had good skills of selecting and applying proper stone blocks for particular purposes. Blocks used in load-bearing structures were exceptionally well shaped and fitted. On the other hand, those skills varied. The frieze from the Romanesque church in Czchów is rather primitive. The size of limestone blocks used in the clergy house in Morawica is strikingly similar to those of various Romanesque edifices in Kraków. It seems, therefore, that those blocks could have been quarried and shaped in quarries located in the city, where the masonry “industry” was well developed. Larger, irregular blocks, used as foundations and filler in the “opus emplectum” type walls were probably quarried on site. Moreover, stones used in more eminent edifices (churches, castles) were probably more carefully selected. The Morawica castle (clergy house) and many churches in Kraków were built of limestone blocks without cherts.

    Opis:
    The early mediaeval period witnessed a considerable breakdown in masonry techniques and in architecture in the Polish territory: the application of stone and developing of skills of shaping rocks into regular cuboid stone bricks. Only local stones quarried within a distance of ca. 15 km from Krakow were used in early mediaeval edifices in the city. They were: two varieties of limestones (Upper Jurassic) and three varieties of sandstones of the Carpathian flysch (Cretaceous to Palaeogene). Sedimentary environments (facies) and post-sedimentary processes determined compactness, block divisibility and workability of stones, which, further on, determined their application. Thin bedded sandstone and platy limestone yielded easily workable and relatively small (few to a dozen of centimetres in length) and quite regular bricks used in the earliest buildings. Rocky limestone was a source of irregularly shaped clumps used initially as a filler of walls erected in the opus emplectum technique. Later, it was used also for cutting larger (few tens of centimetres), more regular blocks. Bedded limestone was a good material for obtaining larger (a dozen or two dozens of centimetres) regular bricks used widely throughout the whole early mediaeval period. Blocks (2 or more metres in length) of soft dimension Carpathian sandstone were used for shaping and carving large elements: tombstones, columns, volutes, epitaphs, etc. Techniques of quarrying and stone working developed considerable with time. Initially, slope scree and stone from demolished older ramparts were used. Later, quarries reached deeper beds which yielded larger bricks and blocks. Stone sources "migrated" with time too. The earliest places of excavation were located within the city, e.g. on the Wawel, Skałka and Krzemionki hills. When those deposits were exhausted, mining moved to more distant spots.
