At the beginning of the Kalmar Union age Sandemar was owned by the Teutonic Order of Livonia. Erik Axelsson Tott bought all the Order's property in Sweden in 1467. During the 1500s the ownership was unknown. In the 1600s the Sandemar belonged to families Oxenstierna, Bonde and Falkenberg. The Royal Council and president Gabriel Falkenberg completed the present main building around the year 1693. Sandemar is today privately owned by Karin Mattson Nordin, daughter of the real estate developer John Mattson.
The main building of Sandemar is made of wood, covered with tiles and the water side plates to protect against sea winds. The farm escaped the Russian ravages in 1719, probably through the deterrent effect of the nearby Dalarö Fortress had, and have therefore preserved the Carolinian period decorations. The English garden is added later with greenhouse, vegetable and fruit tree plantations.References:
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.
