When looking at Frankfurt's skyline, one building clearly strikes out, mainly because it is more than half a millenium older. St. Bartholomew's or "Kaiserdom" (Imperial Cathedral), as it is mainly called in Frankfurt, is a Catholic church. The name Kaiserdom goes back to the 14th century. From 1356 onwards, emperors of the Holy Roman Empire were elected here in this church as kings in Germany, and between 1562 and 1792, emperors were crowned here.
The cathedral was built in the 14th and 15th centuries on the foundation of an earlier church. In 1867, it was destroyed by a fire and then rebuilt in its present style. It was then heavily hit during the allied bombardmends in WWII. The church was then reconstructed in the 1950s.
The church is open throughout the year and can be visited whenever no service is going on.
The spire is 95 meters high, and there is a narrow spiral staircase leading all the way up the tower. If you suffer neither from claustrophobia (the staircase really is quite narrow, especially when visitors walking into the other direction want to pass) nor acrophobia and also don't mind getting a bit dizzy from spiralling up 324 steps, you will be able to enjoy a magnificent view over the city. It is usually open from April until October.
