Schloss Prankh, Renaissance castle in Sankt Marein-Feistritz, Austria.

Schloss Prankh is a Renaissance castle in Sankt Marein-Feistritz formed by combining two medieval structures into one cohesive building. The surrounding grounds still show traces of former water defenses that once protected the property during earlier times.

Schloss Prankh likely arose in the 11th century beside Burg Feistritz, the main defensive structure of the Mareiner Boden, as a seat of the knights von Pranckh, later barons and counts. In the 13th century the complex was enlarged, and sources long mention two separate castles protected by a moat. In 1562 the two independent buildings were combined into a single Renaissance structure. After passing through several owners, it was already described in 1815 as a decayed little castle; in 1838 it went to the Weinmeister family and in 1896 to the Ritter von Leuzendorf, who carried out long-overdue repairs.

The castle was home to the Pranckh noble family for centuries and served as their regional power base and administrative heart. Today, visitors can see from the outside how the architecture reflects this period of authority and governance.

Schloss Prankh stands in the village of Prankh near Sankt Marein-Feistritz, in the Seckau area of Styria. It is a private estate run as a forestry and estate administration, so visits are limited to viewing the Renaissance exterior from the surrounding lanes.

The castle's water defenses were so effective that Turkish raiders, who repeatedly struck the St. Marein area, never dared attack it. Part of the Pranckh family stayed on here while the main seat moved to Burg Pux in the upper Mur valley in 1425.
