Buchanan Castle is a ruined country house in Stirlingshire. The house was commissioned by James Graham, 4th Duke of Montrose and built in 1852-1858 as a home for the Montrose family, serving as such until 1925. It was built as a replacement for Buchanan Auld House, which is located 0.8 km to the northwest but was destroyed in a fire in 1852. The old house and surrounding lands had been the property of the Clan Buchanan but passed to the Clan Graham in the late 17th century. The roof of the building was removed in 1954 and the condition of the house has since deteriorated, but it remains the seat of the Clan Graham.

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.
