The church St. Thomas (German: Thomaskirche) is a Protestant church in the Kreuzberg district of Berlin. Friedrich Adler designed and built the church between 1865 and 1869.^[1] The church was constructed in the shape of a Latin cross with two towers and a 56 metre high dome.^[2]

Prior to the construction of the Berliner Dom, it was the largest church in Berlin with around 3,000 seats, and the congregation was one of the largest in Western Christendom.^[3]

St. Thomas was partially damaged by an aerial bombardment on 22 November 1942.^[4] The church’s eastern gallery and choir windows were completely destroyed.^[5]   The reconstruction occurred between 1956 and 1963 by Werner Retzlaffand Ludolf von Walthausen. The exterior of the church was reconstructed according to historical templates, while the interior underwent several changes.^[5]

It is located directly between the Luisenstädtischer Kanal and Mariannenplatz, once a central location.^{[citation needed]}
