Schloss Wildenberg, Castle and architectural heritage monument in Wildenberg, Germany.

Schloss Wildenberg stands on the western tip of the Schloßberg, about 25 m above the valley floor, in the municipality of Wildenberg in the Kelheim district. The buildings are grouped in a ring around an inner courtyard. The round bergfried that once stood in the middle of the courtyard was completely removed by Georg von Lindheimer in the early 19th century; parts of the late-medieval Zwingermauer with four half-round shell towers survive.

Schloss Wildenberg was built from 1272 on the initiative of the Regensburg cathedral chapter by Hänslin Ebran von Lauterbach; his descendants, who called themselves Ebran von Wildenberg, held the Hofmark until the line died out in 1605. In 1504 Thomas von Löffelholz von Kolberg took the castle for Duke Albrecht IV during the Landshut War of Succession without devastating it, and it was spared plundering in the Thirty Years' War. After secularisation the Bavarian state sold it in 1813 to Major Georg von Lindheimer; Baroness Alix von Kesling bequeathed it to the Free State of Bavaria in 1945.

The castle was built from 1272 on the initiative of the Regensburg cathedral chapter by Hänslin Ebran von Lauterbach, whose family took the name Ebran von Wildenberg and held the Hofmark until 1605. The bronze statue of Baron von Kesling, made by Johann Halbig in 1844, has stood in the courtyard since 1949.

The castle sits on a hillside and requires some physical effort to reach, so comfortable walking shoes are recommended. Visitors should come prepared for changing weather conditions typical of the Bavarian countryside.

The round bergfried that once stood in the courtyard was completely removed by Georg von Lindheimer in the early 19th century, so no tower remains today. What visitors see instead are parts of the 15th-century Zwingermauer with four half-round shell towers and the 16th-century ring wall, now reduced to a terrace.
