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:
The Externsteine (Extern stones) is a distinctive sandstone rock formation located in the Teutoburg Forest, near the town of Horn-Bad Meinberg. The formation is a tor consisting of several tall, narrow columns of rock which rise abruptly from the surrounding wooded hills. Archaeological excavations have yielded some Upper Paleolithic stone tools dating to about 10,700 BC from 9,600 BC.
In a popular tradition going back to an idea proposed to Hermann Hamelmann in 1564, the Externsteine are identified as a sacred site of the pagan Saxons, and the location of the Irminsul (sacral pillar-like object in German paganism) idol reportedly destroyed by Charlemagne; there is however no archaeological evidence that would confirm the site's use during the relevant period.
The stones were used as the site of a hermitage in the Middle Ages, and by at least the high medieval period were the site of a Christian chapel. The Externsteine relief is a medieval depiction of the Descent from the Cross. It remains controversial whether the site was already used for Christian worship in the 8th to early 10th centuries.
The Externsteine gained prominence when Völkisch and nationalistic scholars took an interest in the late 19th and early 20th centuries. This interest peaked under the Nazi regime, when the Externsteine became a focus of nazi propaganda. Today, they remain a popular tourist destination and also continue to attract Neo-Pagans and Neo-Nazis.
