Slane Castle

Slane Castle is situated in the village of Slane in Ireland. The current castle stands on lands with a deep past, overlooking the River Boyne and lying close to ancient Neolithic sites such as Newgrange, as well as the historic area of the Battle of the Boyne.

The original ownership of the land belonged to the Fleming family, a Catholic lineage that supported the Jacobite cause during the late 17th century conflicts. Following the Williamite victory over the Jacobites at the Battle of the Boyne in 1690, the Flemings lost the estate. In 1701, the castle was built by William Burton Conyngham and his nephew, the 1st Marquess Conyngham, on these confiscated lands. The Conynghams were Protestant Scots who had moved to Ireland during the early 17th-century Plantation of Ulster. Around the time of the castle’s foundation at Slane, they shifted their primary residence from County Donegal to this estate, which they have retained for over 300 years.

A significant rebuilding effort took place in 1785. This reconstruction was overseen by prominent architects of the time, including James Gandon, James Wyatt, and Francis Johnston. Johnston also designed the gothic-style Mill Hill gates just east of the castle. In more recent history, a serious fire damaged the castle’s eastern wing facing the River Boyne in 1991. Restoration work took about a decade, with the castle reopening around 2001. Additionally, in 2003, a cannon connected to the castle’s history was recovered from the nearby river.

Nearby, the site includes remnants of a 15th-century religious structure known as St. Erc’s Hermitage, a multi-storey chapel located between the castle and the village church. Close to the hermitage lies an ancient well, historically associated with the Irish god Dian Cecht and the mythical healing tribe called the Tuatha Dé Danann. Over time, this well became Christianized and is now known as Our Lady’s Well.

Since 1981, the grounds of Slane Castle have been used for large outdoor concerts, beginning under the direction of the Earl of Mount Charles, later the 8th Marquess Conyngham. These events have drawn audiences as large as 80,000 people, taking advantage of the natural amphitheatre formed by the castle’s sloping terrain.
