Schloss Favorite is a Baroque hunting lodge built from 1717 to 1723 for the sovereign Duke of Württemberg, Eberhard Ludwig. The architect was Donato Giuseppe Frisoni.
From 1806, King Frederick I of Württemberg converted the park into a ménagerie, including deer and chamois. The architect Nikolaus Friedrich von Thouret renovated the building's interior in neoclassical style.
In the 20th century, the house was neglected and fell into disrepair. It was restored from 1980 on, and opened to the public in 1983.
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.
