Church of Saint Thomas of Canterbury, Medieval church in Mohelnice, Czech Republic

The Church of Saint Thomas of Canterbury is an oriented single-nave building in Mohelnice, with a Romanesque nave core from before 1247 and a long Gothic chancel added in the first half of the 14th century. A massive square tower 72 m high adjoins the north side of the nave; the chancel has a net rib vault and the nave a four-bay cross rib vault.

The nave masonry dates from before 1247, when the church was first recorded in a papal document as the parish of the Assumption of the Virgin Mary, the oldest known parish in northern Moravia. Hussite troops burned it in 1424, killing defenders and people sheltering inside; it was rebuilt in Gothic style and reconsecrated in 1480. The dedication to Thomas Becket, murdered in his cathedral, recalls the townspeople's fate.

The church serves as a gathering place for worship and community events in Mohelnice today. It remains an active center for religious life while connecting the town's medieval past to its present-day residents.

The church is centrally located in Mohelnice and easily accessible on foot from most parts of town. It remains actively used for worship, so visitors should check locally for service times before entering.

The building is officially designated as a cultural monument of the Czech Republic, reflecting its architectural and historical value. This protected status emphasizes that it holds importance beyond its religious purpose for the nation's heritage.
