Cathedral of St. Bartholomew
Cathedral of St. Bartholomew is a 14th century historic church that had over 300 years of service as the coronation site for holy Roman emperors. This fascinating—and free to visit—landmark is filled with rich history and breathtaking architecture. It’s one of the only buildings that has maintained its structure after World War II, due to the immediate reconstruction in the early 1950s. For €2, you can enter through the back of the church to climb the high tower, which has fabulous views (and is a great workout.)
