In the 70s of XIX century the main Lutheran church in Hamburg was the tallest building in the world. From a distance, the church looks familiar. However, it is in ruins. St. Nicholas' Church is not restored deliberately, it was turned into a memorial to the victims of war and tyranny of the 1933 - 1945 period. Nearby there are halls, where the history of the church and the military history of Hamburg can be learned. Since September 2013 permanent exhibition of "Gomorrah 1943 - the destruction of Hamburg in the air war" takes place in there.
The top of the bell tower can be reached by a panoramic elevator. A great view on the port and the Alster Lake opens from there. The museum regularly hosts concerts.
