Burg Alt-Leonroth, Castle ruin in Sankt Martin am Wöllmißberg, Austria

Burg Alt-Leonroth is a rectangular castle site with a ring wall featuring three arrow slits for crossbows. The area contains foundations of multiple ancient buildings and is surrounded by steep slopes and the gorge below.

The castle was built at the end of the 12th century by the Krems family to protect the road crossing the Teigitschklamm gorge toward Pack. It later lost importance and declined into the ruins visible today.

The ruins show medieval building methods through their preserved ring walls positioned above the Teigitschklamm gorge. Visitors can understand from the structures how the castle once functioned and what role it played in the region.

The ruins are accessible through marked paths near Lippenjakl farm, though careful footing is needed due to steep terrain. Wear sturdy shoes and allow time for exploration, as the ground is uneven and filled with old structures.

Small-scale digs at the presumed site of the courtyard cistern and a room built against the ring wall yielded pottery from the second half of the 13th to the 16th century. Metal surveys in 2004 and 2006 produced six projectile points and a dagger crossguard dated between the 13th and 15th centuries. No finds can yet be assigned clearly to the High Middle Ages.
