The Glehn Castle or manor was established by Nikolai von Glehn on the northern part of the lands of his Jälgimäe Manor to become his new residence. The castle was completed in 1886 and was designed by himself. The castle is surrounded by a park with several buildings like palm house (1900–1910), observatory tower (1910) and sculptures Kalevipoeg (1908), Crocodile (1908), all of those designed by Glehn himself.
After Glehn emigrated to Germany in 1918 the castle was looted and fell into decline. In the 1960s, restoration of the building commenced. The renovated palace was inaugurated on the 24 March 1977.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.
