The restored house at the centre of James Joyce's famous short story The Deadwill be unveiled later this evening by the Taoiseach, Mr Ahern, and the Dublin Lord Mayor, Mr Royston Brady.
Number 15, Usher's Island, the home of Joyce's aunts, Mrs Lyons and Mrs Callanan and her daughter Mary Ellen, was saved from dereliction by a Dublin lawyer, Mr Brendan Kilty, over four years ago.
Although the building is Georgian and 250 years old, restorers chose to recreate the Victorian splendour in which Joyce's relatives would have lived.
The project was overseen by Mr Kilty and drew on the knowledge of experts such as Mr Arden Gantley, the art director from Mr John Heuston's film adaptation of the story, which starred Mr Donal McCann and Ms Angelica Heuston.
While the revival of the "dark, gaunt house" on the South quays of the Liffey received no local government or State funding, restorers managed to raise the funds for expensive structural work that is expected to preserve the building for at least another 200 years.
The restoration of 15 Usher's Island took four years to complete and coincides with James Joyce's Bloomsday centenary celebrations.
Organisers of tonight's event are inviting guests to dress up in turn-of-the-century costumes, while the public can view the unveiling from the nearby James Joyce Bridge from 8 p.m. onwards.
The Deadis lauded by many critics as Mr Joyce's supreme short story and presents the Morkan sisters entertaining friends and family at their annual dinner dance.
