Lochranza Castle dates from the 13th century when it was owned by the MacSweens. In 1262, King Alexander III granted the castle and its lands to Walter Stewart, the Earl of Menteith. It is believed that Robert the Bruce landed at Lochranza in 1306 on his return from Ireland to claim the Scottish throne. By 1371, the castle was the property of Robert II. It is thought that at this time it was used as a royal hunting lodge.
During the 1490s, James IV used the castle in his campaign against the Lord of the Isles and the Clan MacDonald. In 1614 it was occupied by James VI and in the 1650s it was used by Cromwell. By 1705, Lochranza Castle was the property of the Hamilton family, after it was purchased by the Duchess of Hamilton. The Hamiltons had owned other estates on the Isle of Arran so eventually sold it to the Blackwood-Davidson family who used it as their principal seat. During the 18th century, the castle fell into disuse and was abandoned. The castle is now in the care of Historic Scotland.

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.
