Gendarmenmarkt is a square in Berlin and the site of an architectural ensemble including the Konzerthaus (concert hall) and the French and German Churches. During World War II, most of the buildings were badly damaged or destroyed. Today all of them have been restored. 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. The Konzerthaus Berlin is the most recent building on the Gendarmenmarkt. It was built by Karl Friedrich Schinkel in 1821 as the Schauspielhaus. Like the other buildings on the square, it was also badly damaged during World War II. The reconstruction, finished in 1984, turned the theatre into a concert hall. Today, it is the home of the Konzerthausorchester Berlin.
