The Wetzlar Cathedral in the middle of the old town attracts attention from afar. The reason: the unfinished facade, which shows red sandstone, green formwork stone and plastered surfaces in other places. In addition, the left tower has so far only been built up to the base level, and the stairway ramp is missing from the large central portal. Particularly noticeable is the empty space behind the facade, adjacent to which are remains of the late Romanesque basilica that previously stood on this site and was demolished in favor of the new building. At the end of the 14th century, construction work came to a halt due to financial problems of the city. Even after that, construction progress repeatedly stalled for decades.
