Othon I of Grandson (1238-1328) expanded the fortress and the power of his lordship.
The castle was owned by the House of Savoy (1389-1420) and from 1420 by the House of Chalon, an ally of the Burgundian Duke Charles the Bold.
The Swiss defeated the Burgundian troops in 1476 at the Battle of Grandson. Bern and Fribourg occupied Grandson. The castle was the residence of their bailiffs until 1798.
A foundation is responsible for the maintenance of the castle nowadays. The castle houses the Grandson Museum. (Source and further information: www.chateau-grandson.ch).
