Baltyboys House is a mansion built in the Georgian style. The estate sits on one hundred acres in Blessington, County Wicklow. It is located a mile from Russborough House, near Poulaphouca Reservoir.
The estate was previously owned by the Smiths, a gentry family. Elizabeth Grant Smith, the wife of Colonel Henry Smith, wrote extensively about managing the estate, particularly during the Great Famine. Dame Ninette de Valois, the great-granddaughter of Elizabeth Grant Smith, was born at Baltyboys.
In January 2014 the estate sold for €4.925 million by the owner, Elizabeth McClory, daughter of Vincent O'Brien and second wife of Kevin McClory. Baltyboys was not listed on the market, instead being sold through a private auction at Christie's.
