Overlooking the River Boyne, just a few kilometres upstream from Newgrange and the site of the famous Battle of the Boyne, Slane Castle in its existing form was constructed under the direction of William Burton Conyngham, together with his nephew The 1st Marquess Conyngham. The reconstruction dates back to 1785 and is principally the work of James Gandon, James Wyatt and Francis Johnston. Francis Johnston was also the architect responsible for the gothic gates on the Mill Hill, located to the east of the castle. The Conynghams are originally a ScottishProtestant family, who planted in Ireland in 1611, during the Plantation of Ulster in County Donegal. With that, the family asserted control over lands around the village of Mountcharles, near Donegal Town in the south of County Donegal. Concurrently, the then head of the family, Charles Conyngham, renamed the village in his own honour as Mountcharles. The family also controlled an extensive estate in West Donegal, especially in The Rosses district. The association between the Ulster-Scots Conynghams and the Slane Estate in County Meath dates back over 300 years, ever since the property was taken by the family following the Williamite Confiscations in 1701. Around that time, the family moved their main ancestral seat south from County Donegal in west Ulster to Slane. Prior to this, Slane Castle had been in the possession of the Flemings, Anglo-Norman Catholics who had aligned themselves with the Jacobites in the War of the Grand Alliance, and thus after the Williamite victory, their property was eligible for confiscation. Christopher, 17th Baron Slane, was the last Fleming Lord of Slane. The present owner of the castle is Henry Conyngham, who styles himself as The 8th Marquess Conyngham. The eldest son of Lord Conyngham is Alex, Earl of Mount Charles. In 1984, Irish band U2 took up residence at the castle to write and record their album The Unforgettable Fire. In 1991, a fire in the castle caused extensive damage to the building and completely gutted the eastern section facing the River Boyne. The castle reopened in 2001 after the completion of a ten-year restoration programme. In 2003, a cannon associated with the castle was found in the nearby River Boyne On the eastward side of the castle demesne, directly between the River Boyne and the village's Church of Irelandchurch in Slane, lay the ruins of St. Erc's Hermitage, a 15th-century multi-storey chapel, and with some 500 metres westward of St. Erc's Hermitage an ancient well can also be found. In one of the central texts of Irish mythology, the Cath Maige Tuireadh, this well is said to have been blessed by the God Dian Cecht so that the Tuatha Dé Danann could bathe in it and be healed, allegedly healing all mortal wounds except decapitation. However, with the arrival of Christianity in Ireland, and the policy of Christian reinterpretation for traditionally pagan sites, the well is now more commonly referred to as Our Lady's Well.
