Villavellid Castle is located on a little hill next to the village. By its diposition and characteristics it can be dated to the 15th century and it was probably the residence of a nobleman. Its constructor isn't known although in 1452 a Don Francisco de Almazán, Marquess of Alcañices, was mentioned as the Lord of the village and the owner of a 'strong house'.
Its plan is a square with wide walls of ashlar masonry on the outside. The corners are reinforced by cylindrical towers except one which is reinforced by the square keep which is very reduced at the present time. This all makes the castle in everything very similar to Fuente el Sol Castle. The entrance to the courtyard is by a pointed arced gate, located near the keep. The entrance to the keep is on a higher floor level and would have been accessed by means of a, disappeared, movable wooden footbridge. Inside the tower several wooden floors existed. Also traces of lean-to constructions are observed in the walls around the courtyard.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.
