The first castle at Fosteau was erected in the 14th century. In approximately 1380 Wauthier de Semousies became owner when Duchess Joan of Brabant gave it to him. His successors were the lords of Zwenne, de Marotte, de Henry and de Jamblines. They built several other buildings around the castle. The hall is Gothic.
The castle became a protected monument in 1979. Since 1980, it has housed an exhibition of antique furniture. Everything within the castle is also available for sale.
References:Dryburgh Abbey on the banks of the River Tweed in the Scottish Borders was founded in 1150 in an agreement between Hugh de Morville, Constable of Scotland, and the Premonstratensian canons regular from Alnwick Abbey in Northumberland. The arrival of the canons along with their first abbot, Roger, took place in 1152.
It was burned by English troops in 1322, after which it was restored only to be again burned by Richard II in 1385, but it flourished in the fifteenth century. It was finally destroyed in 1544, briefly surviving until the Scottish Reformation, when it was given to the Earl of Mar by James VI of Scotland. It is now a designated scheduled monument and the surrounding landscape is included in the Inventory of Gardens and Designed Landscapes in Scotland.
David Erskine, 11th Earl of Buchan bought the land in 1786. Sir Walter Scott and Douglas Haig are buried in its grounds.
