Saint Procopius church, Romanesque church in Starý Bydžov, Czech Republic

Saint Procopius Church is a massive single-nave Romanesque church with a polygonal presbytery and a small bell turret above it. A large tower with three tiers divided by exterior cornices stands at the entrance facade, and traces of two original Romanesque towers remain in the nave walls.

The original church was built in Romanesque style at the turn of the 13th century. It was substantially rebuilt in Renaissance style in the 16th century, when it was raised, the original twin-tower facade was demolished and a single massive tower was added at the entrance front. In 1587 Brikcí z Cimperka cast a bell named Pražan for this tower; Baroque alterations followed in the 18th century. The parish was no longer served by a resident priest in the second half of the 20th century and was administratively dissolved on 1 January 2008, when Starý Bydžov was attached to Nový Bydžov.

The church is a Roman Catholic filial church, no longer served by a resident priest; the parish was administratively dissolved on 1 January 2008 and Starý Bydžov was attached to Nový Bydžov. Regular services ceased, and the building is now used only for funerals and occasional special services. The bell named Pražan, cast in 1587 by Brikcí z Cimperka, hangs in the tower.

Regular services ceased over time; the church is now used only for funerals and services on special occasions, so visits depend on those events rather than fixed opening hours. The parish was administratively dissolved on 1 January 2008 and Starý Bydžov was attached to Nový Bydžov, so enquiries go through the Nový Bydžov parish.

The masonry of the nave still holds traces of the original pair of Romanesque towers, demolished when the church was rebuilt in the 16th century. The single massive tower added to the entrance façade then received its bell, named Pražan, cast in 1587 by Brikcí z Cimperka.
