Slane Castle (Irish: Cáisleán Bhaile Shláine) 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 events within the surrounding gardens with the Irish Independent claiming in 2004 that "Slane today is the kind of internationally recognised venue that can claim even Madonna's attention". The grounds form a natural amphitheatre.
