Stargard Castle is the northernmost preserved hilltop castle in Germany and the oldest secular building in Mecklenburg-Vorpommern at the same time with the deepest dungeon tower in northern Germany. It was built in the 12th and 13th centuries.
During the Thirty Years' War, the castle served as headquarters for Johann t'Serclaes, Count of Tilly, general of the Imperial forces, later becoming a seat of ducal administration. The town suffered during the general decline of the region in the aftermath of the Thirty Years' War.
The castle is now a major tourist attraction in the area, with spectacular views from the tower and special events such as an annual knights' tournament.
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.
