svatý Haštal

The most striking fact about St. Castulus Church is not just its Gothic silhouette, but the long thread of reinvention it has endured since the 14th century. Founded in the late medieval city as a church dedicated to Saint Castulus, this building has been reworked, burned, rebuilt, and repurposed, standing today as a layered record of Prague’s religious and architectural shifts.

Castulus Church, or Kostel svatého Haštala, sits on Castulus Square in the heart of Prague’s historic core. The present structure is a complex of four naves with a tower rising above the western side of the southern nave, and a sacristy tucked to the north of the presbytery. The exterior reads as a calm, plainer shell, yet the interior reveals a dialogue between styles.

The church is primarily stone, with parts of the presbytery and northern nave in brick and block, and a length of 33 meters. The double nave measures about 8 meters wide, while the southern nave reaches roughly 9 meters, and the interior height of the main nave and presbytery sits around 18 meters. Its birthdate is fixed in the late 14th century, with construction dating from roughly 1375 to 1399.
