Killeen Castle dates back to the 12th century as a historic estate.

The Jack Nicklaus Signature Golf Course at Killeen Castle officially opened in 2008, marking its modern development as one of Ireland’s premier parkland golf destinations

At roughly 7,000 yards from the championship tees, the layout plays as a par-72 that suits a wide range of skill levels — challenging experienced players while remaining fair and enjoyable for mid-handicappers. Signature holes incorporate water on multiple sides, tree-lined fairways, and generous yet subtle green complexes that emphasize strategy over pure length

Killeen Castle is ideally located in the lush countryside of County Meath, Ireland, often referred to as the heart of Ireland’s Ancient East. Just about 30 minutes from Dublin Airport 

Unlike links courses that border the coast, Killeen Castle’s parkland terrain features gently rolling fairways, mature trees, and strategically placed water hazards that create a classic inland golf experience. The course is meticulously maintained with immaculate turf conditions year-round, benefiting from rich Irish soil and expert agronomy.
