The so-called Barbarossa Wall in Aachen is an approximately 30 meter long, free-standing section of the inner city wall. It was built in 1172. Emperor Friedrich I (Barbarossa) granted the imperial city the right to mint, market and city in 1166, relieving her of her promise to protect herself with a wall. While two gates and several defensive towers still exist from the outer city wall ring today, but there are hardly any wall sections left, this is exactly the opposite with the inner city wall. There are no towers or gates here, but there are still numerous wall sections. The reason for this is the erection of the second fortification ring from 1257 onwards. From this point on, the citizens built directly on the old, inoperative inner city wall and thus saved an entire wall of houses. This can also be found in the so-called Barbarossa wall, which merges into the interior of the Magellan restaurant towards the west. The still existing rampart at the top of the wall expands in this area to a private roof terrace. The section of the wall had grown over the past few decades. In particular, deep rooting required extensive renovation and stabilization of the medieval masonry. The measurement image documentation that I carried out served the restorers as documentation of the current condition. They planned their work based on these photos and also settled them for them.
