Little Ice Age - Opis:
- The early medieval stronghold in Kalisz was established in the ninth century among the branches of meandering Prosna river. The stronghold's castle was located on the floodplain terrace of Prosna river at an altitude of 100-108 m asl. In the tenth and eleventh centuries numerous redevelopments within the town occurred. In the early thirteenth century, as a result of fightings among dukes, the stronghold was exposed to destruction. Long-term flooding (1221-1223) resulted in the change of the main Prosna river channel. Prosna no longer assured the settlement with defensive functions. The above, and subsequent invasion of duke Henry I the Bearded (Henryk Brodaty) on Zawodzie in 1233, determined moving the castle on a fluvial terrace, in today's center of Kalisz.
