Situated in the port of Pornic, Château de Pornic has long been a symbol of the town. The castle is privately owned and not open to the public. The castle is bordered on one side by the sea and is constructed on a defensive site. In the Middle Ages, it provided for the defence of the port.
In the 10th century, Alan Wrybeard, Duke of Britanny, built and fortified a wooden castle. It was occupied by a garrison who protected the entrance to Pornic. In the 12th century, it was the property of the Lords of Rais who rebuilt it in stone. In the 15th century, it belonged to Gilles de Rais but was confiscated by the Duke of Britanny at the time of his trial. In the 18th century, it belonged to Marquis de Brie Serrant whose properties were confiscated during the French Revolution. The castle fell into ruin. The castle was bought at the end of the 19th century by Monsieur Lebreton, founder of the seawater baths, and restored by the architect François Bougoüin who gave it its present appearance with its fully arched windows dressed in brick in the style of the Italian architecture of the Château de Clisson.References:
Louisenlund is a site with one of Denmark's largest collection of megaliths. Some 50 stones standing upright among the trees, many of them over 2.5 metres high. The megaliths, which bear no inscription, stand on low mounds or over graves where the remains of burnt bones are buried. In the early Bronze Age and late Iron Age (1100 BC), it appears to have been common practice to set megaliths over graves of this kind. The stones stand alone or in small groups. As the site has not been archeologically investigated, it is not known why the stones were raised there. Another important megalithic site on Bornholm is Gryet, a small wooded area 5 kilometres west of Nexø. Originally it had more than 60 megaliths. Some have now been removed while half those remaining have fallen to the ground. The highest of them, once standing on the mound towards the south of the wood, was removed in the 17th century to be used as a gravestone. Louisenlund was bought by King Frederik VII when he visited Bornholm in 1851. He named it after his mistress, Countess Louise Danner.
