Rathaus, Picture 2, Hamburg, Sachsen, Germany, 2014

This is not a church, but Hamburg's city hall, or Rathaus. Built between 1886 and 1897, and designed by Martin Haller (1835-1925), who also designed the American Consulate, it survived World War II intact. One interesting anecdote is that in 1971, a secret room was found in the tower, leading to theories that there could be more. Officially, there are already 647 rooms known.
