Burg Wiesentfels, Medieval castle in Hollfeld, Germany.

Burg Wiesentfels is a medieval castle in Hollfeld, Bavaria, built on a steep rock above the Wiesent valley. The remains include sections of defensive walls and building foundations that reflect several construction phases over the centuries.

In 1333 Knight Albert von Giech received Wiesentfels from the Bishopric of Bamberg as a fief. In 1412 two thirds were granted as Unterwiesentfels to Heinz von Schaumberg, and in 1415 one third as Oberwiesentfels to Hans II von Giech. Hussite raids in 1433 left Oberwiesentfels described as desolate; it vanished from the fief books in 1467. Rebuilt from 1476 to 1481, the castle was burned by rebellious peasants in 1525 and rebuilt in the old style by Achaz von Giech. The counts of Giech held it until 1938.

The castle gave its name to the village of Wiesentfels below it, now a district of Hollfeld. From 1333 the site was held as a Bamberg fief by the lords of Giech, who kept it, later as counts, until the last count died in 1938. The castle is privately owned and closed to visitors until May 2027.

Burg Wiesentfels is privately owned and, as of September 2026, closed to visitors until May 2027. Plan any visit for after that date; the castle stands on a 40-metre rock above the Wiesent valley near Hollfeld.

The castle sits in the Franconian Switzerland region, where limestone rocks push up directly beneath the walls and were used as part of the structure itself. This means the boundary between the natural rock and the built wall is often impossible to tell apart at close range.
