History+
The origins of Bothwell Castle date back to 1160, when King Malcolm granted the Lordship of Bothwell to the Olifard family. After the death of Walter Olifard in 1242, ownership passed to Walter of Moray, who had married Olifard's daughter. Moray began constructing the Great Donjon, the oldest part of the castle, intended to be the center of a planned but uncompleted complex. A prison tower was also erected. From 1296, the castle was repeatedly contested, besieged, and captured in the Scottish Wars of Independence, by both Scottish and English forces.
