St Aubin's Fort was developed on a rocky islet off the coast at the western end of St Aubin's Bay. It was finished in the 1540s. At that time St Aubin was the primary port on Jersey and the fort controlled the entrance. In the 17th century the Civil War the Parliamentarians turned it into a stronger fortress, by building a bulwark on it, and when the Royalists regained possession they replaced this with granite ramparts and added a storey to the tower. In the 18th century, and again in the 19th, the fort was rebuilt twice, but in peaceful Victorian times it was let as a summer residence. In the Second World War the Germans strengthened the fort with turret guns and concrete casemates.
A causeway extends from the road in front of the Royal Channel Islands Yacht Club to the fort, and one can walk out at low tide. However, the fort itself is closed to the public. Jersey's Sea Scouts use the fort as a headquarters, storing their sails and other equipment in a German bunker built into the fort. They have also converted a room in the tower into a classroom.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.
