Ardgillan Castle and Demesne is Ireland’s hidden gem. Set in spectacular parklands overlooking the Irish Sea with a magnificent view of the Mourne Mountains.   As well as the castle, the demesne features a walled and rose garden both of which present an orderly profusion of colour.

The ‘castle’ is a large eighteenth century country-style house with castellated embellishments. Originally named ‘Prospect House’ the central section was built by Robert Taylor in 1738, with the west and east wings added in the late 1700s.
