Burgstall Saalenstein, Medieval castle ruin in Landkreis Hof, Germany.

Burgstall Saalenstein is a medieval castle ruin perched on the steep riverbank of the Saale near Hof. Visible remains include foundation walls, a vault carved into the embankment, and traces of defensive earthworks.

The fortress dates to the 12th century and later became a boundary stronghold between regions. Excavations uncovered bronze objects and coins that document early occupation of the site.

The name Saalenstein refers to the Saale river and the rocky spur above it. In 1524 the Saale here formed the border of the Margraviate of Brandenburg-Kulmbach, and the castle held the role of a Kastell. The nearby Fattigsmühle, called the 'little Saalenstein', was probably another outwork of the castle before Eustachius von Zedtwitz converted it into a mill.

The ruins stand on private land behind a closed lattice gate, so visits must be arranged with the owner, who runs a restaurant at the foot of the hill by the Saale. The Autobahn 72 runs across the castle hill itself, so the site is reached by car rather than on foot from the motorway.

The modern Autobahn 72 runs directly across the castle hill, creating an unusual contrast between medieval ruins and contemporary infrastructure. Stone walls and the moat have been incorporated into the surrounding garden design.
