Iveagh House

Grafton Street & St Stephen's Green

The headquarters of the Department of Foreign Affairs occupies two splendid Georgian houses that were joined together by Benjamin Guinness when he bought them in 1862 as his city residence. No 80 – the house on the left as you look at the building – was designed by Richard Cassels in 1736. The house was given to the Irish state in 1939 by Benjamin's grandson Rupert.
