Tum Collegiate Church

The Collegiate Church of St. Mary and St. Alexius is an encastellated Romanesque church located in the village of Tum near Łęczyca, in central Poland. It was constructed out of granite blocks and sandstone in the mid-12th century.

The church was built using the opus emplectum technique. It has the form of an aisled basilica with galleries, a twin-tower west façade, and two apses. It was reconstructed in the 15th, 18th and mid-20th centuries; during the latest reconstruction the church returned to its simpler Romanesque form and round turrets at the east were added. The main portal is sculpted and dates back to the first half of 12th century.
