Major conservation and restoration works are under way in Georgian Leinster House.

The Office of Public Works (OPW) is addressing structural and architectural issues in the 270 year old building to protect it and ensure it can continue to serve as home to the Houses of the Oireachtas. All Oireachtas business continues as usual, however guided tours are limited.

Scaffold on Leinster House

About the project

Construction on Leinster House began in 1745. It was designed by Richard Cassels, also known as Richard Castle, as the town house of James FitzGerald, the first Duke of Leinster. Over the years it has been extended and adapted to meet the needs of its various occupants, including the Royal Dublin Society and later the Houses of the Oireachtas. The wear and tear on the fabric of the 270 year old House, and the need to address it, has become evident.

Seanad Chamber relocated to National Museum

Seanad Chamber relocated to National Museum

Georgian Leinster House has been vacated, and the Seanad Chamber has been relocated temporarily to the ceramic room of the National Museum on Kildare Street. When Seanad Éireann was first established, in 1922, it was temporarily accommodated in the museum before moving to Leinster House. A steel door, previously concealed behind a partition, has been uncovered and put back into use to allow Senators and staff to move between the buildings.

The house,
of which this stone is the foundation,
James, twentieth Earl of Kildare,
caused to be erected in Molesworth's field,
in the year of our Lord 1747.
Hence learn, whenever, in some unhappy day,
you light on the ruins of so great a mansion,
of what worth he was who built it,
and how frail all things are,
when such memorials of such men cannot outlive misfortune.
