St. Mary's Church & Astronomical Clock

Marienkirche Rostock

Rostock's largest brick Gothic church. Its astronomical clock, built in 1472, still runs on its original mechanism and is the city's top attraction.

St. Mary's Church is a masterpiece of northern German brick Gothic architecture, built between the 13th and 15th centuries. Its interior is tall and bright. Behind the altar stands an astronomical clock made in 1472. It is the only clock of its kind in the world that still runs on its original mechanism. The calendar dial was set to run until 2017 and was later replaced, extending it to 2150. At noon and midnight, figures of the Apostles parade around it. The church also has a bronze baptismal font and a Baroque organ. Admission is a small fee. Climbing the tower is seasonal. Allow 40 to 60 minutes for a visit.
