The Château de la Motte-Glain was built by Pierre de Rohan-Gié in 1495 on the site of an older fortress belonging to the lords of Rougé. Anne of Brittany and Charles VIII stayed there in 1497 and Charles IX and Catherine de' Medici in 1565. It was bought in 1635 by par Michel Le Loup, counsellor to the Parlement of Brittany. The castle was modified by Pierre de Rohan-Gié in the 17th century.
The castle includes a gatehouse composed of a central pavilion flanked by two round towers, some ruined buildings (including a storeroom and a press), a residence decorated with Renaissance windows from the 15th century. The chapel contains a fresco from the 16th century.
The castle is privately owned. Parts of it (gatehouse, storeroom, press, chapel, residence, bay, roof, wall) have been listed since 1926 and protected since 1929 as a monument historique by the French Ministry of Culture. It is open to the public in the summer months.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.
