Slane Castle is located in the village of Slane, within the Boyne Valley of County Meath, Ireland. The castle has been the family seat of the Conyngham family since it was built in the late 18th century, on land first purchased in 1703 by Brig.-Gen. Henry Conyngham.
It holds the Slane Festival within its grounds, with the Irish Independent claiming in 2004 that "Slane today is the kind of internationally recognised venue that can claim even Madonna's attention". Its sloping lawns form a natural amphitheatre.
