Lord of the Dance creator Michael Flatley is understood to have bought Castlehyde House near Fermoy in north Cork for a sum believed to be about £3 million.
Although auctioneering sour ces would only confirm the house had been sold, local sources confirmed they were told by the former owner last week that Flatley had bought the house.
Boston-born Flatley, who sprang to fame with his performance in Riverdance, was seen visiting the house a number of times in the past few weeks.
The house was built in 1801 and is set on 150 acres of pasture and woodland on the banks of the Blackwater. It was the ancestral home of Ireland's first president, Douglas Hyde.
Flatley - who grossed more than £120 million from his Lord of the Dance spectacular which played to 3 million people - is expected to move into the magnificent three-storey manor shortly.
He already has houses in London, France and the US but has been looking for an Irish home for some time and only last month visited historic Whitehall House near Skibbereen in west Cork.
He joins a long list of people from the world of entertainment who have bought houses in the south-west.
