Home to the Brabazon Family (the Earls of Meath) since 1618 Killruddery House is the most know Elizabethan-Revival mansion in Ireland and also one of the earliest.
The Gardens at Killruddery are the oldest in Ireland still surviving in their original 17th century unique style together with 18th and 19th century additions. The Gardens were designed for the entertainment of a large number of people and therefore the scale is comparable to that of a park. The Gardens should be regarded as mainly the work of the 4th and 6th Earls. A French Landscape architect named Bonet, a pupil of Le Notre, was known to have been employed by the Earl of Meath in 1682.
