About Ardgillan Castle
Although referred to as a Castle, the residence at Ardgillan is a large country-styled house with castellated embellishments. Originally named “Prospect House”, the central section was built in 1738 by Robert Taylor, with the west and east wings added in the late 1800s.
Initially, the site was heavily wooded, the name Ardgillan being derived from the Irish “Ard Choill” meaning High Wood. It was cleared out by service soldiers and itinerant workers in return for one penny a day, sleeping accommodation, and one meal.
The house consists of two storeys over a basement which extends out under the lawns on the southern side of the building. When occupied, the ground and first floors were the living accommodations while the west and east wings were servants’ quarters and estate offices. The basement comprised of the service floor, the kitchen, and stores. The Castle has now been restored and the ground floor rooms and kitchens are open to visitors for guided tours.
