Burg Spitzenberg, Medieval castle ruin on Spitzenberg mountain in Kuchen, Germany.

Burg Spitzenberg is a castle ruin located on the mountain of the same name near Kuchen in Baden-Württemberg. The remains show surviving wall sections and foundations that belonged to a medieval fortified settlement built on a hilltop.

The castle was the seat of the Spitzenberg family, related to the Zähringen and the Counts of Helfenstein; Bishop Gottfried von Spitzenberg was a noted member. It is said to have been destroyed as early as 1311, yet finds from the site date mainly to the late 14th century. The Schwäbischer Albverein excavated the ruin in 1913 under Konrad Albert Koch; most of those finds are lost, though parts are held in the Geislingen local history museum.

The castle gave its name to the Spitzenberg family, related to the Zähringen and the Counts of Helfenstein; Bishop Gottfried von Spitzenberg was its best-known member. The ruins are unmaintained and still show traces of the 1913 excavation by the Schwäbischer Albverein under Konrad Albert Koch.

The ruin stands on the 665-metre Spitzenberg, a southern edge height of the Filstal valley west of Kuchen. It is reached on foot; the surviving wall remains lie on the summit and are not maintained, so expect rough ground and overgrown spots. Sturdy footwear helps on the climb.

Archaeological finds from the 14th century were uncovered during excavations and some are displayed in the Geislingen Local History Museum. These objects reveal details about how medieval inhabitants lived and their connections with neighboring areas.
