Originally home to The Butlers of Dunboyne, the original Castle on the Dunboyne Estate was destroyed during the Cromwellian invasion of Ireland as a result of the family's refusal to convert to Protestantism. The Georgian house that we see today was completed in 1764 by Drogheda architect George Darley. Some of the finest works from the Lafranchini Brother's ornamental stucco plasterwork is on display. The ceiling over the staircase depicts the four elements to life at this time; War, Music, Education & Love.
The last of the Butlers to reside in the Castle was the 22nd Baron of Dunboyne John Butler, Catholic Bishop of Cork. Since then the Castle has passed through many families - the Butler-O’Briens, Sadlier, Morrough-Ryans and the Watchmans. In 1955, it became home to the Good Shepherd Sisters who remained here until 1991 when it was bought by the Keating family, before the present owners bought it in 1999. It was in need of much repair and was lovingly restored to its original state and opened as Dunboyne Castle Hotel & Spa in 2006.
