Lübeck is a city in northern Germany. It's renowned for its Brick Gothic architecture, dating to its time as the medieval capital of the powerful Hanseatic League trading confederation. Lübeck’s symbol is the circa-1478 Holstentor city gate, which defended the river-bounded Altstadt (old town). St. Mary's Church, completed in 1350, widely influenced Northern European church design. It was rebuilt following WW II.
