Culzean Castle in Ayrshire was used as the castle of Lord Summerisle. Culzean is mainly seen in exterior shots although a scene was filmed in one of the first rooms you enter while going round the castle. Most of the interiors of Lord Summerisle's castle were filmed at Lochinch Castle in Dumfries and Galloway.

From Ayr take the A719 south. After 5 or 6 miles you will see a signposted turnoff on the right of the road to Culzean Castle and Country Park. Admission charge in 2000 was very expensive at £7 to castle and grounds or £3 to just the grounds. Frankly I don't think it is at all worth the money to enter the castle especially as no photography is permitted inside.
