Altmannstein Castle Ruins The Lords of Stein are mentioned in documents as early as the 12th century, but due to the frequency of this place name in this area, concrete conclusions are difficult to draw. The castle was built and named after Count Altmann II of Abensberg in 1232. His grandson Ulrich II sold the castle in 1291 to Duke Ludwig of Bavaria, the later emperor. From 1340 onwards, it was pawned, first to the Hautzendorf family, then again to the previous owners from Abensberg. In 1446, the Nurembergers conquered the castle during their campaign against the robber barons of the Regensburg region. The last Count of Abensberg, Niclas, was caught between the warring Wittelsbachs and was murdered in 1485 on the orders of the Bavarian Duke Christopher the Strong of Bavaria-Munich. During the Thirty Years' War, the castle was destroyed by the Swedes in 1632, and it has remained in ruins ever since. In 1911, the architect Georg Wirth acquired the ruins and had a historicist residential building built there – typical of the period. In 1991, the complex was extensively renovated by the municipality. Today, the complex is entered via a wooden bridge that leads to the outer bailey. Its entrance area is covered by buildings from 1911, intended to create a historic impression, but originating from the castle romanticism of the turn of the century. Behind it lies the most impressive part of the castle: the mighty keep, made of 18 m high, made of humped ashlars. Its walls are 3 m thick, and the entrance is 4.5 m high. It protected the access area to the inner bailey. Unfortunately, the tower is not accessible. Behind it is the palace, built of ashlars and rubble. The mix of building stones suggests a later construction using stones from an earlier building. A few remnants of defensive and moat walls also remain. The unusual location of a rectangular tower made of rubble stone outside the castle at the foot of the castle rock is unusual. It was probably part of a later wall connecting the town.

Quaint castle, it's a shame the Christmas market is no longer held here.
