The Freudenberg castle was one of the largest castles in region. The main castle dates from the first half of the 13th century and consists of a keep with a trapezoid floor plan. The curtain wall was 80m long and 60m wide and protected by a round tower in the southwest corner.
The castle was built by the Lords of Wildenberg. Later it was owned by several families and the imperial Austria. Because of a dispute over the legacy of the last Count of Toggenburg Freudenberg was besieged on May 26, 1437 by troops from Zurich. The castle was taken by the besiegers, plundered and set on fire.
Since 1985 the site has been owned by the municipality of Bad Ragaz and can be visited freely.
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.
