Slane Castle, Ireland, 1991 ... St. Paul’s Cathedral, considered the mother church of London, was severely damaged in the Great Fire of London in 1666.

Lord Henry Mount Charles, scion of one of Ireland’s foremost aristocratic families, turned the imposing family seat Slane Castle in Co Meath into the country’s best-known outdoor rock venue.

In 1981, Slane was put on the map when Slane Castle hosted its first rock concert. Forty years later, how does it balance leaving a legacy while focusing on sustainability?

Lord Mount Charles, who organised era-defining rock gigs at his Slane Castle home, has died aged 74, his family confirms.
