In a city of contemporary high rises with modern, clean lines, the Eschenheimer Turm certainly stands out as a piece of the distant past. This medieval tower, which was built in the early 15th century as part of a much larger fortification structure, sits unexpectedly in the middle of Frankfurt’s bustling downtown. In the 19th century, most of the fortress was demolished as it was no longer being used for military defense, but pleas from Count d'Hédouville, the French ambassador at the time, saved the Eschenheimer Turm from a similar fate. Today, the 47-meter-high tower is an important city landmark, and its ground floor even contains a bar and restaurant.
