Aub Town Fortification

The town fortifications of Aub have an almost completely preserved closed ring wall made of quarry stone masonry, which was built between 1404 and 1436. In the north, the Gollach forms a natural moat. The town is most strongly fortified on the western flank in the area of the castle. There was a Zwinger (outer bailey) system there, which was fortified by a second wall and of which only a few tower stumps remain. The former wall height was 11 m with a thickness of 1.50 m. Of the formerly 15 towers, 11 are still preserved, including the keep at the castle and some half-shell towers. The towers usually had half-timbered upper floors, which were mostly added in the 19th century. Most towers were designed as round towers. The few rectangular towers mostly had simultaneous residential and thus guard use.
