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 city walls of Avila were built in the 11th century to protect the citizens from the Moors. They have been well maintained throughout the centuries and are now a major tourist attraction as well as a UNESCO World Heritage Site. Visitors can walk around about half of the length of the walls.
The layout of the city is an even quadrilateral with a perimeter of 2,516 m. Its walls, which consist in part of stones already used in earlier constructions, have an average thickness of 3 m. Access to the city is afforded by nine gates of different periods; twin 20 m high towers, linked by a semi-circular arch, flank the oldest ones, Puerta de San Vicente and Puerta del Alcázar.
