Sint-Nicolaaskerk, Romanesque church in Potvorov, Czech Republic

Sint-Nicolaaskerk is a Romanesque church in Potvorov with solid stone walls defined by characteristic rounded arches typical of the period. A bell tower added in 1825 creates a distinct vertical element that marks the building's profile against the sky.

The church was probably founded in the first half of the 13th century, on the initiative of the Hrabišic brothers Všebor IV and Kojata IV. A document of 1281 records it as fortified and linked to the neighbouring stronghold. Hussite wars damaged it and destroyed the Romanesque tower; a Baroque porch followed in 1741, a sacristy in 1785 and a Neoclassical tower in 1825–26.

The church is a filial church of Kralovice since 1952. The Spolek pro románský kostel v Potvorově, founded in 2007, continues the work of the 1901 association for the church's reconstruction, raising funds for repairs and a new bell. The New Nicholas bell rings noon daily, and all three bells ring on major feasts.

The church sits in the small village of Potvorov and is easily reached by car or on foot since it occupies a central location. Visitors should note that access may be limited when services are taking place.

The oldest bell, cast in 1489 by Master Jiljí of Prague, is the church's oldest movable monument. A 2011 public collection paid for the New Nicholas bell from the Dytrych workshop in Brodek u Přerova; it rings noon daily, and all three bells sound on major feast days.
