Schloss Abensberg, Medieval water castle in Abensberg, Bavaria, Germany

Schloss Abensberg, also called Burg Abensberg, is a former water castle at Aventinusplatz 6 in the southeast corner of Abensberg. Its 120 × 80 m site is split into a lower Vorburg and a higher Hauptburg about 60 × 60 m, separated by a deep moat crossed by a three-arched brick bridge. The east and south outer walls were part of the town fortifications.

The castle was first recorded in 1256 and suffered heavy damage during the Thirty Years' War. Today, sections from the 13th and 14th centuries still remain standing.

The castle chapel was dedicated to Saint Nicholas, documented in 1423 as a two-storey structure; it had already disappeared by the early 18th century. The name Abensberg comes from Babo II von Abensberg, the town's founder, who died in 1080. His descendant Ulrich III had the town walls built with 32 round towers and 8 corner towers, one for each of Babo's 32 sons and 8 daughters.

A brick-arched bridge provides access to the castle grounds, where you can explore the remaining medieval structures and fortification elements. The visit is best during daylight hours to fully appreciate the details of the historic walls and moat.

Archaeological excavations in 1998 unearthed the foundations of a keep from 1436 and the former location of Saint Nicholas chapel, documented in 1423. These discoveries reveal that the castle was once more complex and extensive than the remains visible today.
