Property of the Day: Cassillis Estate, Ayrshire
THE PROPERTY: From a high bank, Cassillis towers over the River Doon. The impressive building is approached through electric gates via a private drive that follows the river through immaculate grounds.
THE LOCATION: The castle is a short distance from the coast and the popular sailing area of the Firth of Clyde, with yachting marinas at Troon, and further up the coast at Largs and Inverkip.
THE INTERIOR: Laid out over five floors, the rooms of the castle (which include a ballroom) have huge windows and fine plasterwork.
WHY WE LOVE IT: The spiral staircase is part of the original Keep of Cassillis, and is built clockwise to ensure an easy defence by a right-handed swordsman. There is also a secret staircase that is not marked on the layout plans and leads up to the East Chintz Room.
