Castillo de San Miguel is located in Almuñécar and is bounded by the remains of the original city walls. The castle sits on a small hill, which is difficult to access. The original fortifications date of 1st century BCE. During the Moorish occupation, the castle was enlarged to include towers and three gates.
At the end of the reign of the Catholic King Ferdinand in the 16th century, more was added (the moat, the drawbridge and the front entrance with its four round towers). During the war of independence against the French, it suffered the bombing of the British troops. The ruins later became used as a Christian cemetery. The keep, which was on the inside, is demolished. There is a small museum within the castle grounds.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.
