Schloss Jägerhof was built between 1748-1772 by the Elector Carl Theodor. He had commissioned architect Johann Joseph Couven from Aachen. In 1796, Jägerhof was sacked by the revolutionary forces and had finally become completely uninhabitable. The building was restored in 1811 on the occasion of Napoleon’s visit to Düsseldorf, according to Adolf von Vagedes’ plans.
Today Jägerhof is a cultural-historical museum devoted to the Classical German writer J. W. von Goethe (1749-1832). Opened to the public in 1956, there are around 800 original artefacts from his life and work are on permanent display. Goethe
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.
