The royal castle of Jungshoved was mentioned in 1231. The annexed church dates from the same period. The castle is thought to have been built as early as in the 1100s as part of King Valdemar I's coastal defences against the Wends (Baltic Slavs). The castle is strategically located at the mouth of Skibbinge Cove. Jungshoved may also have been implicated in the monarch's control of the herring market at Falsterbo. After the Dano-Swedish wars of the 1600s, the castle was in ruins. The last structures were removed in the 1700s and the building materials reused for barracks and stables for Prins Jørgen's Palæ, a three-winged hunting seat in Vordingborg.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
