Uniejów: Castle, City Trail and Spa Zone

• The Castle of the Archbishops of Gniezno is a well-preserved summer residence dating from the 14th century.
• The Collegiate Church of the Assumption of the Blessed Virgin Mary was built in 1349; it contains a tomb of Saint Bogumił dating from 1666.
• The spa zone includes, among other things, a footpath, a combined walking and cycling path, and a kayak landing.
• The geothermal water is almost 70 °C and is extracted from a depth of 2 km.

The Castle of the Archbishops of Gniezno brings together a specific historical function and a striking distinction: it is a well-preserved 14th-century summer residence of the archbishops and is considered one of Poland’s best-preserved medieval defensive structures. Anyone interested in the history of residences and fortifications will find both aspects in a single building.

The Collegiate Church of the Assumption of the Blessed Virgin Mary offers a different architectural focus. The Gothic church was built in 1349, and its chancel retains a 14th-century rib vault. The tomb of Saint Bogumił, commissioned in 1666, is also located in the church. Made of black marble, it depicts the saint as a half-reclining bronze figure in episcopal vestments. The church therefore offers a glimpse both of Gothic architectural features and of a later commissioned tomb.

An English landscape park surrounds the castle. It was created between 1860 and 1870 at the initiative of the owners at the time, the Toll family. This adds a much later chapter of the town’s history to the castle’s medieval building history. The two dates help distinguish between different historical periods.
