President Michael D Higgins has led tributes to Lord Henry Mount Charles, describing his contribution to live music in Ireland as "quite unique" following his death on Wednesday.
In a statement, the President said he was "saddened" to learn of Lord Henry's passing, and praised his vision in transforming Slane Castle into one of the country's most iconic music venues.
"Lord Henry's contribution was quite unique and a very important turning point in live music in Ireland when he decided to begin using the natural amphitheatre at Slane Castle as a venue at which public performances could be held by some of the most contemporary makers of music," President Higgins said.
"It wasn’t just in relation to very well-known events that Henry was involved; he had a deep interest in the promotion of music, including new and young talent."
Lord Henry, formerly The Marquess Conygham, died on 18 June following a long illness. He was 74. In recent years, he spoke publicly and candidly about his experience with cancer, which the President also acknowledged.
"I have been saddened over recent years to hear of his struggles with cancer, about which he spoke personally and helpfully of his experiences," the President said.
He also extended his condolences to Lord Henry's wife, Lady Iona, their children Alexander, Henrietta, Wolfe and Tamara, and to "all his family and friends".
Taoiseach Micheál Martin said in a statement on X: "Lord Henry's vision for Slane Castle resulted in one of Ireland's best music venues, hosting many of the biggest and best concerts this country has ever seen.
"His contribution to music and culture in Ireland was immense."
Tánaiste Simon Harris has also paid tribute to Lord Henry, the man "who brought rock-and-roll to the iconic music venue that is Slane Castle". Harris praised his "unrivalled wit, warmth and generosity", and thanked him for bringing music, culture and pride to Co Meath.
Lord Henry will be remembered for opening the grounds of Slane Castle to historic concerts by acts including Madonna, Queen and The Rolling Stones - placing Ireland firmly on the global live music map.
