Welcome to Markree Castle, a 17th Century authentic Irish castle located in the beautiful County Sligo on the route of the world-famous Wild Atlantic Way. Markree Castle is a place to be inspired, to reflect, to recharge and reconnect. One of the largest privately-owned castles in Ireland, Markree Castle stands on a secluded 500-acre estate in the scenic north-west of Ireland. Wander through the castle, enjoying the blazing fire in the Grand Hall, period features and furnishings, and the breath-taking inter-linked dining rooms creating that authentic, old-world charm. The 500-acre grounds are also all yours to explore with mature trees, meticulously manicured gardens, and even the River Unshin flowing through the castle estate. .
