The Oliemolen (literally Oilmill) is a 16th-century watermill located at the foot of a steep hill in the Aambos. The name already tells us much about its function, extracting oil, but this was not always the case, it first function as a volmolen (a mill to press wool). The mill is fed by the Caumerbeek.
A copy, dating to May 31, 1710, of the original deed exists, indicating the mill was founded on May 9, 1502, commissioned by the family Van Scheasberg. However, names of notables on the deed do not correlate with the people in those positions in the beginning of the 16th century; possibly a '0' was mistaken for a '6', making the founding year 1562.
In 1829 a license was granted for the mill to mill grain, which became to only use of the mill in 1904.
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.
