Tolquhon Castle was built by William Forbes, 7th Laird of Tolquhon, between 1584 and 1589 as an extension to the earlier tower house known as Preston's Tower. Although ruined, the castle has been described as the most characteristic château of the Scots Renaissance. It is in the care of Historic Scotland and is open to the public.
After William Forbes' death his descendants continued to occupy Tolquhon until 1718, when they were forced to move out due to debts incurred by the failure of the Darien scheme. The castle subsequently decayed and is now a ruin.
The main entrance is on the north range of the castle, with the Preston Tower forming the north-east corner. The gallery occupies the first floor of the west range, while the main hall is in the south range, accessed via a stair from the courtyard. A prison was located within the south-east tower. To the north of the main quadrangle is the walled outer courtyard, with the remains of a doocot.

Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
