The estate was the ancestral home of the Taylor family for over 150 years until it was sold to the Dublin County Council in 1982.
The castle is documented to have a resident ghost known as the 'Waiting Lady,' said to watch the sea for her husband's return.
The walled garden features a unique 'glasshouse' structure that was restored to reflect 19th-century horticultural designs.
During the 19th century, the house was significantly remodeled to include the crenelated roofline that gives it its distinct 'castle' appearance.
The demesne contains a designated 'Lady's Stairs,' a bridge crossing the railway line that connects the estate directly to the coastal shoreline.
The grounds incorporate a modern adventure playground designed specifically to integrate with the surrounding natural woodland topography.
Ardgillan Castle is an 18th-century country house situated within a 194-acre public park overlooking the Irish Sea in North County Dublin. Originally built as Prospect House in 1738 by Reverend Robert Taylor, the structure was later renamed Ardgillan. The estate features an extensive Victorian-style walled garden, an ornamental pond, and a rose garden. The park grounds provide a mix of managed lawns, woodland trails, and dramatic cliff-edge views. It serves as a regional venue for arts, crafts, and cultural exhibitions throughout the year. The demesne is maintained by Fingal County Council for public recreation and heritage preservation. The castle interior contains period-appropriate furniture and historical displays focused on the Taylor family's tenure. It occupies a prominent position on the coast between the towns of Balbriggan and Skerries.

Check the official estate notice boards upon arrival for temporary trail closures due to seasonal conservation work.
Do not attempt to climb the cliff faces or access restricted coastal areas beyond the designated footpaths.
The park grounds are open daily, but the castle interior is closed on Mondays during the winter season.
Stay on marked paths in the walled gardens and observe designated zones for dogs, which must be kept on leads in certain areas.
