Burg Rothenfels is a well-preserved medieval fortress built in the 12th century by the Freising Bishops on a dramatic red rocky outcrop overlooking Oberwölz in Austria's Wölzertal region. The castle has retained its original appearance for nearly 900 years, making it exceptionally rare among Alpine fortifications. Today it offers summer accommodations, a garden café with homemade pastries, an adjacent campground, and regular guided tours (Thursdays and Saturdays) featuring historical rooms and valley views. Visitors can explore over eight centuries of regional history within its walls.
