Carton House is a country house and surrounding demesne that was the ancestral seat of the Earls of Kildare and Dukes of Leinster. Located 23 km west of Dublin, in Maynooth, County Kildare, the Carton Demesne is 1,100 acres (4.5 km²). For two hundred years, the Carton Demesne was the finest example in Ireland of a Georgian-created parkland landscape.
