Hohentwiel Castle is a ruin of a former castle on the peak of the dead volcano Hohentwiel. It is located in the region called Hegau, which is close to the Lake of Constance. The mountain overtowers the city of Singen, which is located on the foot of the mountain, by 260 meters. With an overall area of nine hectares, Hohentwiel castle is the biggest castle ruin in Germany which is open for tourists. Since 1990, more than 80,000 tourists have visited the ruin every year; the maximum was reached in 2002 when 126,500 people visited Hohentwiel castle. The annual Hohentwiel-Festival takes place in the fortress area. In its history, the castle was also a ducal seat during the Early Middle Ages and an ordinary castle during the High Middle Ages. The fortress on the Hohentwiel was first mentioned in 915. In the following times, the mountain was in possession of different noble families, such as the House of Zähringen. In the early 16th century, the Hohentwiel was more and more influenced by the House of Württemberg and became ducal seat once more. In the following centuries, the castle was expanded to the fortress of the state of Württemberg and was unsuccessfully besieged five times during the Thirty-Years' War. Later, the castle was used as state penitentiary, until it was slighted during the War of the Second Coalition in 1801. After its destruction, the ruin soon became of interest to tourism.

Hohentwiel is an extinct volcano in the Hegau region of Baden-Württemberg in southern Germany. The mountain is west of the city of Singen and 20 miles (30 km) from Lake Constance. Hohentwiel began forming, along with the chain of volcanoes in the Hegau region, about 7–8 million years ago, when a layer of volcanic ash and stone was laid down. The magma consists of phonolite. In the following millions of years, the core was opened 260 metres beneath the surface by the glaciers from the ice age. This formed the core that is now exposed, after the ensuing millions of years of erosion. Hohentwiel Castle, whose ruins are on top of Hohentwiel, was built in 914 using stone taken from the mountain by Burchard II, Duke of Swabia. Originally, the Monastery of St. Georg was within the fortress, but in 1005 it was moved to Stein am Rhein (now in Switzerland), and the Swabian dukes lost control of Hohentwiel. In the later Middle Ages the noble families von Singen-Twiel (12th–13th centuries), von Klingen (to 1300) and von Klingenberg (to 1521) resided here. In 1521, it was passed on to Duke Ulrich von Württemberg, who developed Hohentwiel into one of the strongest fortresses of his duchy. During this time, it began to be used as a prison, and in 1526, Hans Müller von Bulgenbach, a peasant commander, was imprisoned there before he was executed.The fortress resisted five Imperial sieges in the Thirty Years' War, under the command of Konrad Widerholt between 1634 and 1648. The effect was that Württemberg remained Protestant, while most of the surrounding areas returned to Catholicism in the Counterreformation. The castle served as a Württemberg prison in the 18th century and was destroyed in 1801 after being peacefully handed over to the French. Today the former fortress Hohentwiel is the biggest castle ruin in Germany. The modern-day city of Singen nestles at the foot of the mountain.
