Château de Trémazan was constructed on a rocky outcrop and had a square keep which, following a partial collapse during the winter of 1995, exposed the interior to reveal a habitable tower of four floors, each with one chamber.
The history of Trémazan is intimately linked to that of the du Chastel (or Châtel) family. It was they who built it and made it their principal residence for several centuries. The origins of this dynasty are still shrouded in mist, but with the passage of history, they became very prominent. So much so that Chastels ended up taking their place in the high Breton aristocracy and being counted among the four most important families of the Viscounty of Léon. However, by the end of the 16th century, the elder branch of the family died out for lack of a male heir.
The present castle goes back mainly to the 13th and 14th centuries. The castle would have been built on the ruins of a castellum already existing in the 6th century. According to legend, Tanneguy du Chastel, founder of the abbey at Saint-Mathieu, was born here. The building became a stone castle around the 10th century. In 1220, it was destroyed during the war against the Duke of Brittany, then rebuilt thirty years later by Bernard du Châtel. Sold as national property after the French Revolution, the castle was abandoned in the 18th century. Apart from the 12th century square keep, remains include towers and the outer enceinte dating from the 13th, 14th and 15th centuries.
Today, the non-profit association S.O.S Château de Trémazan attempts to preserve the castle and to increase the knowledge of its past. Thus, samples of the castle beams gave rise to a study of dendrochronology for better dating of the building.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.
