Söderlångvik has been inhabited since the early 16th century. In the past it frequently changed hands. Owners in the sixteenth century were called de Jonsson or Jönsson, in the 17th century Michelsson, Tomasson, Sigfridsson and Faxell-Cronmarck. In the 18th century Söderlångvik was owned for a long period by the Thesleff family and in the early 19th century by the af Petersen and Ramsay families, owners of Björkboda manor.
In 1927 Amos Anderson, famous Finnish businessman and art collector, purchased the manor and farm. The main building was totally reconstructed in 1934-1935. After Anderson’s death ownership was transferred to the art association Konstsamfundet. Today Söderångvik is an art and culture-historical museum. The exhibition tells about Amos Anderson and his art collections. There are also foreign art from the Amos Anderson Art Museum collection in Helsinki.
The Château Comtal (Count’s Castle) is a medieval castle within the Cité of Carcassonne, the largest city in Europe with its city walls still intact. The Château Comtal has a strong claim to be called a 'Cathar Castle'. When the Catholic Crusader army arrived in 1209 they first attacked Raymond-Roger Trencavel's castrum at Bèziers and then moved on to his main stronghold at Carcassonne.
The castle with rectangular shape is separated from the city by a deep ditch and defended by two barbicans. There are six towers curtain walls.
The castle was restored in 1853 by the architect Eugène Viollet-le-Duc. It was added to the UNESCO list of World Heritage Sites in 1997.
