A stunning mansion in the Elizabethan Revival style, Killruddery has been home to the Brabazon family (earls of Meath) since 1618 and has one of the oldest gardens in Ireland. The house is impressive, but the prizewinner here is the magnificent orangery, built in 1852 and chock-full of statuary and plant life. If you like fancy glasshouses, this is the one for you. It's 6km north of Greystones just off the R761 coast road.
The house was designed by trendy 19th-century architects Richard Morrisson and his son William in 1820, and it was reduced to its present-day huge proportions by the 14th earl in 1953; he was obviously looking for something a little more bijou. There are guided tours of the house during the summer (hourly from 1pm to 4pm, July to September), as well as a Thursday night supper club, where dinner is served in the garden by the tea room. There's also an excellent farmer's market every Saturday.
