Leinster House

Since 1922, Leinster House in Dublin has served as the parliament building of the Republic of Ireland, before which it functioned as the headquarters of the Royal Dublin Society.

Leinster House was originally the ducal palace of the Dukes of Leinster. Today, the sole and exclusive power of making laws is vested in the Oireachtas, subject to the obligations of Community membership, as provided for in the Constitution.

The primacy of Dáil Éireann in regard to the life of the Parliament is recognised, in that a general election to Seanad Éireann must take place not later than 90 days after the dissolution of the Dáil.
