Maus Castle construction was begun in 1356 by Archbishop-Elector of Trier Bohemond II and was continued for the next 30 years by successive Electors of Trier. The construction of Burg Maus was to enforce Trier's recently acquired Rhine River toll rights and to secure Trier's borders against the Counts of Katzenelnbogen (who had built Burg Katz and Burg Rheinfels). In the latter half of the 14th century Burg Maus was one of the residences of the Elector of Trier.
Unlike its two neighbouring castles, Burg Maus was never destroyed, though it fell into disrepair in the 16th and 17th centuries. Restoration of the castle was undertaken between 1900 and 1906 under the architect Wilhelm Gärtner with attention to historical detail.
The castle suffered further damage from shelling during World War II which has since been repaired. Today Burg Maus hosts an aviary that is home to falcons, owls and eagles, and flight demonstrations are staged for visitors from late March to early October.
The ward of the castles contains two residential buildings. The vulnerable side facing uphill is guarded by a round bergfried.
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.
