Ardgillan Castle

Ardgillan Castle Bench

Ardgillan Castle and Demesne is Ireland’s hidden gem.

The property is 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.

Ardgillan Castle and Demesne is situated in North County Dublin on an elevated coastline between Balbriggan and Skerries, 32 kilometres north of Dublin City.

The demesne is well signposted off the M1.

The park consists of 194 acres of rolling open grassland, mixed woodland and gardens overlooking the Irish Sea with views of Mourne Mountains to the north and Lambay to the south-east.

Ardgillan is a sanctuary for many species of animals, mammals and birds for which the wooded areas provide a safe retreat from surrounding agricultural land.

Today the demesne is a stunning visitor attraction with a range of facilities the public can avail of, including castle tours, theatre events, afternoon tea, children’s parties plus much more!
