Burg Thalberg, Medieval castle in Dechantskirchen, Austria.

Burg Thalberg is a medieval castle in Dechantskirchen featuring two square towers positioned on an east-west axis as part of its main structure. The site displays typical defensive architecture with thick stone walls and narrow windows characteristic of this period.

Leopold von Erlach had Burg Thalberg built between 1171 and 1180 as a sovereign fief, part of border fortifications against Hungary. The castle is first documented in 1209, when it was held by Leopold's sons Erhard and Heinrich von Krumbach. In 1346 it passed to Ulrich der Tursen, and in the 15th century the Lords of Rottal carried out major alterations and expansions.

The castle incorporates Romanesque architectural elements with thick defensive walls, small windows, and a late Gothic chapel within its complex.

The interior is not typically open to visitors, but you can view the exterior and its structures from outside. Information panels at the site explain the history and architectural features for those interested in learning more.

The eastern keep rises approximately 24 meters and remains visible from several vantage points along the Wechsel pass road. This tall tower serves as a recognizable landmark in the surrounding landscape.
