Leinster House

Leinster House is a mid-18th-century classical mansion on Kildare Street in Dublin that has served as the seat of the Irish parliament (the Oireachtas) since the early 20th century. It is the working centre for both houses of parliament and numerous government offices.

Key interiors include the debating chamber of the lower house (Dáil Éireann) and the upper house (Seanad Éireann), along with committee rooms and offices used for legislative and administrative functions. Parts of the complex are open on guided tours when parliament is not sitting.

Originally built as a ducal townhouse in the 18th century, the building and adjacent additions were repurposed for state use after Irish independence and have been modified to accommodate parliamentary functions. The complex has grown by acquisition and internal adaptation rather than by wholesale reconstruction.

Leinster House sits on Kildare Street near central Dublin institutions such as the National Museum and Trinity College, and is within easy walking distance of central city landmarks.

• Visitor access: Sudden public closures can occur when the parliament is sitting, but guided visits are available on non-sitting days; check ahead for visitor hours.
