The site includes a hunting lodge (Jagdschloss) built in the late Renaissance style by the Dukes of Württemberg.
The monastery's influence reached its peak under Abbot Wilhelm, who maintained close ties with the Papacy.
The sandstone walls feature visible markings from the original 11th-century stonemasons.
During the peak of the Hirsau Reform, the monastery governed over 150 dependent priories.
Klosterruine Hirsau is a significant Romanesque monastery complex in Calw, formerly one of the most influential Benedictine abbeys in Southern Germany. The site features the extensive remains of the St. Peter and Paul monastery, established in the 11th century. Visitors can explore the ruins of the cloister, the chapter house, and the surrounding park grounds. The complex was heavily damaged by fire during the War of the Palatine Succession in 1692. Notable architectural features include the surviving sandstone masonry and the clearly defined floor plan of the former basilica. The site now serves as an open-air historical monument and a venue for cultural events.

Wear comfortable, flat walking shoes as the terrain consists of uneven stone paths and grass.
Visit the small museum adjacent to the site for historical context before walking through the ruins.
Bring a light jacket as the stone walls remain cool even on warm summer days.

The grounds are typically accessible year-round, but specific museum buildings within the complex may have seasonal closures during winter.
Maintain a respectful volume, as the site is an open-air monument; keep to marked paths to preserve the structure.
