Uniejów

Uniejów lies on the Warta in central Poland. It belonged to the archbishops of Gniezno and probably received town rights before 1290. After the Teutonic Knights burned it in 1331, the town was rebuilt; a defensive castle erected in 1360–1365 became an archiepiscopal residence and a place for meetings and councils.

In 1520 Archbishop Jan Łaski united the old town, new town and suburbs. Uniejów later lost some importance as the primates established other residences. The Swedish invasion in the mid-seventeenth century damaged the castle and town, and fires followed in 1736 and 1790. After 1815 it formed part of Russian-controlled Congress Poland.
