IT was once the extravagant home of former Taoiseach Charles Haughey.
But now the Abbeville mansion has been sold for around €5.5m to a foreign buyer.
The plush pad had been on the market for several months.
And the final sale price is a snip compared to the €45m received by the Haughey family when they sold the house and estate in 2004 to Manor Park Homes building firm.
The sale includes the famous 18th Century James Gandon-designed mansion, along with the entire Kinsealy estate of 250 acres.
The house is viewed as being culturally and historically significant given that its designer, James Gandon, was also responsible for the Custom House and the Four Courts.
Abbeville dates from 1770 and its dining room is considered Gandon's "finest surviving domestic interior", according to the National Inventory of Architectural Heritage.
The Haugheys lived at Abbeville for 35 years, during which it became famous for its wine cellar, art collection and Sam Stephenson-designed 'Irish pub'.
The property had been placed on the market by the receivers, Kavanagh Fennells, in the middle of last year, at €7.5m.
It has 14 bedrooms and six reception rooms across 14,600sq ft over four floors.
But the house requires extensive investment and upgrade, which could set the new owner back millions in order to conform with strict heritage guidelines. There is speculation that the Kinsealy estate was acquired by a UK-based investor.
It is believed it will likely be kept as a private luxury home rather than the estate being broken up for development purposes.
Sherry FitzGerald, the estate agency firm which achieved the sale, would not comment on whether a deal had taken place.
Manor Park had planning permission to build a 70-bed hotel, a spa/leisure centre, a championship golf course and new homes, but the planning permission has now expired.
Last year Fingal County Council refused to extend it for five more years.
