Historic Hotels in Portmarnock

Set amidst the rich history of Ireland, Dunboyne Castle Hotel & Spa has a storied past that dates back to the times of The Butlers of Dunboyne. The original castle, which served as their residence, was destroyed during the Cromwellian invasion of Ireland due to the family's steadfast refusal to convert to Protestantism. In its place, a stately Georgian house was constructed in 1764 under the watchful eye of Drogheda architect George Darley. The structure boasts exquisite ornamental stucco plasterwork by the renowned Lafranchini Brothers, with the ceiling over the staircase depicting the four elements central to life during that period—War, Music, Education, and Love.

The last of the Butlers to call the castle home was the 22nd Baron of Dunboyne, John Butler, who was also the Catholic Bishop of Cork. Over the years, ownership of the castle passed through various families, including the Butler-O’Briens, Sadliers, Morrough-Ryans, and Watchmans. In 1955, the Good Shepherd Sisters took up residence until 1991 when the Keating family acquired the property. The Ross family then purchased the castle in 1999 and embarked on an ambitious restoration project. Led by Seamus Ross, they transformed the castle into the luxurious Dunboyne Castle Hotel & Spa, which opened its doors in 2006. In December 2022, Mr. Thomas Röggla added the hotel to his prestigious TMR Hotel Collection, which includes esteemed properties such as Farnham Estate Spa & Golf Resort, Harvey’s Point, Mount Wolseley, Aghadoe Heights, and the Ballymascanlon Hotel & Golf Resort.
