The German Church (in German: Deutscher Dom) is located to the south of the Gendarmenmarkt. It has a pentagonal structure and was designed by Martin Grünberg and built in 1708 by Giovanni Simonetti. This church belonged to the Lutheran community. It too was modified in 1785 by Carl von Gontard, who built the domed tower. The German Church was completely destroyed by fire in 1945, during World War II. After German reunification it was rebuilt, finished in 1993 and re-opened in 1996 as a museum of German history.
