Reinegg castle was built in the mid-13th century, and is recorded in 1263 as being owned by the countess Elisabeth von Eppan. Ten years later, ownership was transferred to count Meinhard II of Tyrol. Over the centuries, fiefs were granted to a number of different families until in 1635, Reinegg castle came under the ownership of Bolzano merchant David Wagner. In 1861 the Wagner family was elevated to Counts of Sarthein; they owned Reinegg castle until 1936 when it was sold. The castle is privately owned and not open to the public.
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.
