Thorberg Castle with outbuildings, Medieval castle and correctional facility in Krauchthal, Switzerland
Thorberg Castle is a fortified site on a rocky outcrop south of Krauchthal village, combining elements from several building phases spanning from medieval times to modern periods. The ensemble includes the main castle, former monastery buildings, and outbuildings that together form a significant architectural composition.
The castle was first documented in 1175 as a noble residence and was converted into a Carthusian monastery in 1397. In the 19th century the site was repurposed as a correctional facility, a function it continues to serve today.
The former monastery chapel features frescoes from the early 16th century showing religious scenes like the Adoration of the Magi and Shepherds, reminding visitors of its monastic past.
The site currently operates as a correctional facility for male inmates serving extended sentences and is not open to the public. Visitors can view the exterior and surrounding landscape from outside the secure perimeter.
The site preserves visible remnants of a historical sandstone quarry showing evidence of medieval stone extraction techniques and tool marks. These quarrying marks reveal the hands-on craftsmanship and material sourcing that supported the castle construction.
