Saint Thomas of Canterbury church in Sulejów, Gothic church in Sulejów, Poland

Saint Thomas of Canterbury church in Sulejów is an oriented three-nave basilica with a transept and a rectangular presbytery, built before 1232. Its cross-ribbed vaults mark the transition from late Romanesque to early Gothic, and the original Romanesque main portal survives. The church adjoins the former Cistercian monastery on its south side.

The Cistercian monastery and its church were founded in 1176 by Casimir the Just, who brought the monks from Morimond. The church was built before 1232, the year of its dedication. Fires in 1790 and 1847 destroyed it, and each time it was restored. In the 1980s its poor condition forced its closure for worship and visits.

The church is named after Saint Thomas of Canterbury, a dedication tied to the Cistercian order that was brought to Sulejów from Morimond in 1176. The monastery complex, including the church, was listed as a Historic Monument of Poland in 2012. The interior furnishings are largely Baroque, contrasting with the Romanesque main portal and Gothic vaulting.

The church is located in Sulejów and welcomes visitors who want to explore the building. Regular services are held throughout the week, so it is wise to check visiting times before planning your trip.

In 2012 the church and Cistercian monastery were entered on Poland's list of Historic Monuments by decree of the President. The monastic complex, with its fortifications and former gardens, is counted among the country's most valuable monuments, and the church shows the passage from late Romanesque to early Gothic through its ribbed cross vaulting.
