Set in the countryside of East Cork, Castlemartyr Resort is a five-star hotel located on approximately 220 acres of landscaped parkland. The property centres on an 18th-century Manor House and sits beside the ruins of Castlemartyr Castle, a structure dating back to the 13th century.

The estate has a long and complex history, with connections to prominent Norman families and figures associated with the wider history of East Cork, including Sir Walter Raleigh. The present-day resort opened to guests in 2008 following extensive restoration and redevelopment of the manor house and surrounding grounds.

Accommodation includes over 100 guest rooms and suites within the hotel and manor house, along with a collection of private residences on the estate. Rooms are notably spacious, starting at roughly 500 square feet, with the largest suites extending to several thousand square feet. Interiors combine period features with contemporary finishes and modern amenities.

Dining at Castlemartyr focuses on seasonal Irish produce, with multiple restaurant and bar options across the hotel and manor house. The resort has earned recognition in leading food guides, reflecting its emphasis on quality ingredients and refined presentation.

The estate is also home to Castlemartyr Golf Club, an 18-hole, par-72 course measuring approximately 6,728 yards from the championship tees. Designed by Ron Kirby, the course is laid out in an inland links style, offering a challenging but accessible experience for golfers of varying abilities. Facilities include a clubhouse, practice areas, and a fully stocked pro shop.

Castlemartyr Resort today operates as a luxury country retreat, combining historic architecture, modern accommodation, dining, spa facilities, and championship golf within a restored Irish estate setting.
