Leinster House - The Irish Parliament

Originally built for the Duke of Leinster in 1745, the building’s Kildare Street façade resembles that of a large town house. Bought by the Royal Dublin Society in 1815. The government obtained it in 1922 for parliamentary use and bought the entire building two years later. Visitors can arrange to tour the main rooms, including the Seanad chamber, and can sit in the public gallery in the Dáil.
