Slieve Gullion welcomes visitors for its Footsteps in the Forest Halloween experience. Anne Marie McAleese also hears about the huge burial cairn at the summit of Slieve Gullion, known as The Calliagh Berra's House, which is the highest surviving passage tomb in the UK or Ireland. Deirdre Donnelly reports on the story of a young curate from Derry, George Vaughan Sampson, who escaped the court of Louis XVI and Marie Antoinette just before the French Revolution. He returned to Derry where he became headmaster of the city’s first school and later became rector of the Church of Ireland in Aghanloo near Limavady. Recently, his last resting place has been discovered, forgotten for almost 200 years, by Roe Valley historians, Betty and Matt Ferguson. Presented by Anne Marie McAleese.
