Russborough House

Russborough House is a stately house situated near the Blessington Lakes in County Wicklow, Ireland, between the towns of Blessington and Ballymore Eustace and is reputed to be the longest house in Ireland, with a frontage measuring 210 m/700 ft. It is an example of Palladian architecture, designed by Richard Cassels for Joseph Leeson, 1st Earl of Milltown and built between 1741 and 1755. The interior of the house contains some ornate plasterwork on the ceilings by the Lafranchini brothers, who also collaborated with Cassels on Carton House.
