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 Leinster House, the current seat of the Oireachtas (Irish parliament), built by Richard Cassels in 1745 is Kildare Street's most important building. The Archaeology and History section of the National Museum of Ireland and the National Library of Ireland are located on either side of the Leinster House and were built in 1885.
