Festung Hohentwiel, Medieval fortress ruins on volcanic mountain in Singen, Germany.
The stone fortification spans nine hectares across multiple levels, featuring defensive walls, courtyards, and military structures on a phonolite peak.
The fortress, first documented in 915, withstood five sieges during the Thirty Years' War before French forces orchestrated its destruction in 1801.
The fortress ruins host an annual summer festival with performances, bringing thousands of visitors to experience music within ancient stone walls.
Visitors can reach the fortress through marked hiking trails from Singen, with guided tours available from April through October.
The structure stands as Germany's largest fortress ruins, rising 260 meters above Singen with views extending to Lake Constance and the Alps.

Baden-Württemberg offers a wide range of destinations beyond the usual routes. The region includes medieval castle ruins such as Hohentwiel, Hohenbaden, and Yburg, medieval monasteries like Maulbronn and Alpirsbach, and palaces such as Lichtenstein and Weikersheim. Geological formations shape the landscape: the Blautopf displays a karst spring with distinctive water color, the Wutach Gorge cuts through limestone layers, and Wimsen Cave lies in the Danube Valley. Numerous waterfalls including Urach Falls and Menzenschwand Falls complement the natural offerings. The region combines historical and contemporary elements. The Wildline suspension bridge spans the Enz Valley, the Rottweil Test Tower serves as an elevator testing facility and viewing platform, and the historic Sauschwänzlebahn railway runs on a track featuring loops and tunnels. Parks such as Hohenheim Gardens and Rosenstein Park offer botanical collections. The market square in Freudenstadt displays typical Black Forest architecture, and the Neubulach Silver Mine provides insights into historic mining operations. These destinations allow detailed exploration of the region's nature, history, and engineering.
