Sophienkirche
The Sophienkirche is a Protestant church built according to the concept and plans of master builder Philipp Gerlach. The church was built in 1712-13 and was originally consecrated as the 'Spandau church'. It was only under the successor of King Friedrich II (1740-1786) that it was named after Sophie Luise and has since been called Sophienkirche. The baroque church tower was added in 1732-1734 by the master-builder Johann Friedrich Grael. On 13 September 1964, the American civil rights activist Martin Luther King preached in the Sophienkirche during a surprise visit to East Berlin.
