Step into the heart of Irish democracy at Leinster House, the official seat of the Oireachtas (the parliament of Ireland) in Dublin. Built between 1745 and 1748 as Kildare House for James FitzGerald, Earl of Kildare (later the first Duke of Leinster), this impressive structure originally served as an aristocratic residence.
Designed by architect Richard Cassels, with later elements by Isaac Ware, it holds a grand place in architectural history: its first and second floors served as the floor model for the White House, designed by Irish architect James Hoban. Before becoming the meeting place for Dáil Éireann and Seanad Éireann in 1922, it functioned as the headquarters for the Royal Dublin Society.
As you explore its historical context, you will learn about its past connections to figures like Lord Edward FitzGerald, a national icon of the 1798 Rebellion. On the grounds facing Merrion Square, you can reflect on Ireland's path to independence beside a grand triangular monument dedicated to founding figures Arthur Griffith, Michael Collins, and Kevin O'Higgins.
