Schloss Pertenstein, Architectural heritage monument in Traunreut, Germany.

Schloss Pertenstein is a castle in Traunreut that blends medieval defensive structures with aristocratic living spaces. Tall towers, thick stone walls, and carefully crafted facade details shape its outward appearance.

Ritter Engelbrecht von Taching built a castle around 1290 on the west bank of the Traun, opposite the Traunwalchen church, naming it Perchtenstein after his wife Perchta von Stein. In 1383 it passed by inheritance to the Toerring family, who still own it. Around 1600 Barbara Lucia von Toerring-Stein expanded it into a Hofmarkschloss with arcaded west wing; the arcades were walled up and reopened in the 1970s.

The castle serves as a venue for art exhibitions and cultural events that bring together locals and visitors interested in regional creativity. These gatherings celebrate contemporary and traditional craftsmanship from Bavaria.

Schloss Pertenstein stands between Matzing and Traunwalchen on the west bank of the Traun, in the Traunreut district of Pertenstein. The castle and the Marstall hall are rented for private and cultural events, so access depends on the event; the Marstall hall was rebuilt after a fire in 2002. The castle chapel of St. Anna and Maria, first documented in 1598, belongs to the complex.

The arcades of the west wing, built around 1600 from Italian Nagelfluh conglomerate, were walled up for centuries and only reopened in the 1970s. A red marble tablet from 1601 in the inner passage to the arcade courtyard records the expansion under Barbara Lucia von Toerring-Stein.
