The first reference to a castle in the village of Penne dates from 825 AD and its first known señor was Geoffroi, mentioned in 1096 in documents related to Raymond, Count of Toulouse. Throughout the Middle Ages (5th to 15th centuries) the site of Penne was of military strategic importance, being situated on the borders of the provinces of Albigeois, Quercy and Rouergue, with its fortress perched atop a cliff overlooking the River Aveyron.
The castle remained in use, seeing repeated conflicts, such as the Hundred Years War(1337-1453) between England and France, and the French Wars of Religion (1562–1598) between Protestants and Roman Catholics during which it was partly destroyed. It was then abandoned for approximately 400 years.
The remains of the castle include the dungeon, the ramparts and a chapel.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.
