Kildare Street (Irish: Sráid Chill Dara) is a well-known street in Dublin, the capital city of Ireland close to the principal shopping area of Grafton Street and Dawson Street, to which it is joined by Molesworth Street. Some Irish government departments have their offices on this street but it is most famous for Leinster House, built by Richard Cassels in 1745, the current seat of the Oireachtas (parliament).
