St. Nicholas Church (Nikolaikirche) Rostock

"The St. Nicholas Church was the center of the Slavic settlement area in medieval Rostock. Built as an early Gothic hall with four bays in brick, it was consecrated in 1312, initially without a tower and without a choir.

The half-integrated square west tower was added in the 15th century. It was originally built with a 75-meter-high pointed roof. The tanner's chapel, which was initially built as a sacristy, also followed. The choir in the east was raised to create a passage for the Lohgerberstraße. The Schwibbogen was created.
The building, which was restored in 1893, was badly damaged in a bombing raid in 1942. The nave and the tower burned down, only the choir remained undamaged.
In 1952 the tower was given a pyramid roof with a baroque lantern. From 1976 onwards, the St. Nicholas Church was extensively renovated. reconstructed and retained several special features: The church's administrative rooms are located in the tower and the high Gothic hall roof houses 20 apartments.
Unfortunately, not much of the furnishings have been preserved due to the war damage. The Gothic-style high altar is currently in St. Mary's Church and can be viewed there. The nave is now a concert hall and the newly designed churchyard is an inviting place to relax." Source: ostsee.de/rostock/nikolai-kirche.html

There are really great apartments in the roof!

The Nikolaikirche in the Hanseatic city of Rostock was built from 1230 and is therefore one of the oldest surviving hall churches in the Baltic Sea region. It is one of the three surviving large parish churches in the city and is named after Bishop Nikolaus von Myra. Like the Marienkirche and the Petrikirche, it belongs to the Evangelical-Lutheran inner-city parish of Rostock in the priory of Rostock in the Mecklenburg church district of the Evangelical-Lutheran Church in northern Germany. Church services are only occasionally held there. It sees itself as a supra-communal, spiritual and cultural center of the city, open to church and other cultural uses and is mostly used as a concert church.
