Castletown is Ireland’s largest and earliest Palladian style house. Built between 1722 and 1729 for William Conolly Speaker of the Irish House of Commons and the wealthiest commoner in Ireland.
The faccade was almost certainly designed by the Italian architect Alessandro Galilei while the Irish architect Sir Edward Lovett Pearce added the wings.
The house remained in the hands of the Speaker’s descendants until 1965 when the house was purchased by a property developer Major Wilson.
Fortunately the house was saved in 1967 when along with 120 acres of the demesne lands it was purchased by the Hon. Desmond Guinness founder of the Irish Georgian Society for pound 93000.
The house was opened to the public in the same year and restoration work began funded by the Irish Georgian Society and private benefactors. In 1979 care of the house passed to the Castletown Foundation a charitable trust which was established to own maintain and to continue the restoration of the house.
