City walls of Aachen: photo description (Stadtmauer Aachen)

City walls of Aachen — the once powerful fortification, fortress represent a double ring, which was supposed to protect the city from enemy attacks. Up to the present day, two walls with numerous towers reached only partially. Two of the eleven surviving city gate was badly damaged during the bombing of world war II, but was later restored.

The construction of the inner ring of the city walls began in 1172 with the permission of the Emperor Frederick I Barbarossa, so often this fortress called his name. Serfdom ring total length 2480 m constructed by the method of casting: the space between the two walls from 1.5 to 2.5 meters filled with stones and a special solution. Large areas of the remaining interior walls are in the heart of the University quarter.

As soon the wall of Barbarossa was to limit the growing city, in the late 13th century (exact date unknown), the inhabitants of Aachen has decided to start construction of the second ring of the fortification wall at a sufficient distance from the city. The outer wall also built by way of casting, its length is 5300 meters, and a height of 8-10 meters. For added protection, the outer ring was surrounded by a moat with a width of 24 to 28 metres and a depth of 12 meters. The outer wall had 11 gates and 23 defensive towers, of which only five escaped destruction in the expansion of cities and railway routes in the 19th century.
