Lahneck Castle was built in 1226 by the Archbishop of Mainz Siegfried III of Eppstein to protect his territory at the mouth of the Lahn, where the town of Oberlahnstein and a silver mine had come into the possession of the Archbishopric in 1220. The castle chapel, dedicated to Saint Ulrich of Augsburg, was built in 1245, in the same year the first Burggraf took up residence in the castle.
In 1298, King Adolf of Nassau was a guest at the castle, shortly before his death in the Battle of Göllheim against King Albert I of Habsburg. In order to avenge him, the Burggraf of Lahneck, Friedrich Schilling of Lahnstein, participated in a conspiracy against Albert. The castle was stormed in 1309 and Friedrich Schilling was executed.
According to legend, when the Knights Templar were ordered by Pope Clement V to disband in 1312, the last 12 Templars took refuge in the castle, where they perished in a heroic fight to the death with forces of Mainz Archbishop Peter of Aspelt. In 1332, Pope John XXII granted a 40-day indulgence to those attending services in the castle chapel.
In 1475, Mainz Archbishop Theodoric of Isenburg-Büdingen had the castle strengthened with two outer walls following the Mainz Bishops Feud with his rival archbishop, Adolph II of Nassau. In 1633, during the Thirty Years War, the castle was heavily damaged by Swedish and Imperial troops.
On July 18, 1774, Johann Wolfgang von Goethe wrote the poem Geistesgruß. It was inspired by the sight of Lahneck Castle during his travels along the Lahn River.
In the German Mediatisation of 1803, in which the Archbishopric of Mainz lost its secular territories, Lahneck Castle was granted to the Duchy of Nassau. In 1850 it was sold and has remained in private ownership since. Edward Moriarty, a Director of the Rhenish Railway Company, became one of its first owners. During the ownership of Earl Kleist-Tychow a more than life-sized portrait of Queen Victoria was presented which can still be seen at the castle. Imperial Admiral Robert Mischke, later commander of armoured cruiser 'von der Tann', purchased the castle in 1909 and it has been owned by his family ever since.References:
Varberg Fortress was built in 1287-1300 by count Jacob Nielsen as protection against his Danish king, who had declared him an outlaw after the murder of King Eric V of Denmark. Jacob had close connections with king Eric II of Norway and as a result got substantial Norwegian assistance with the construction. The fortress, as well as half the county, became Norwegian in 1305.
King Eric's grand daughter, Ingeborg Håkansdotter, inherited the area from her father, King Haakon V of Norway. She and her husband, Eric, Duke of Södermanland, established a semi-independent state out of their Norwegian, Swedish and Danish counties until the death of Erik. They spent considerable time at the fortress. Their son, King Magnus IV of Sweden (Magnus VII of Norway), spent much time at the fortress as well.
The fortress was augmented during the late 16th and early 17th century on order by King Christian IV of Denmark. However, after the Treaty of Brömsebro in 1645 the fortress became Swedish. It was used as a military installation until 1830 and as a prison from the end of the 17th Century until 1931.
It is currently used as a museum and bed and breakfast as well as private accommodation. The moat of the fortress is said to be inhabited by a small lake monster. In August 2006, a couple of witnesses claimed to have seen the monster emerge from the dark water and devour a duck. The creature is described as brown, hairless and with a 40 cm long tail.
