1289, and a bad ending
The Italian miners
In 1289, miners from Genoa and Florence arrived in the Silvermines area under sponsorship of the English Crown, looking for silver. They found it, and worked the mines until 1303, when a local man was killed and the community's response ended operations abruptly. The mines sat idle for generations. Seven centuries of intermittent extraction followed, by which point the hills had given up silver, lead, zinc, copper, sulphur, iron, barytes and pyrites - a variety unmatched anywhere else in Ireland.
The Pritties, the burning, and the man who built Ryanair
Kilboy House
Kilboy House was built around 1780 for Henry Prittie MP, later the first Lord Dunalley, to a design by William Leeson - three storeys, five bays, Doric columns on the entrance front. It burned in August 1922 during the Civil War. The rebuilt version lost a storey in the 1950s when funds ran out. Tony Ryan, the Thurles-born founder of Ryanair, bought the estate in the 1980s and began restoring it. A fire in 2005 gutted much of the work. His son Shane had the house reconstructed again to the original three-storey design. It remains private. The ruins of Kilboy Church and the old Prittie graveyard are visible from the road.
Largest in Europe, closed in 1982
The Mogul mine
The 20th-century mining operation at Silvermines, run by Mogul of Ireland from the late 1960s, became the largest base metal mine in Europe at its peak - employing over 500 people, the single biggest employer in North Tipperary. The plant processed 3,000 tons of ore per day. The main Mogul operation closed in 1982; the last working mine, a baryte operation at Magcobar, followed in 1993. The tailings pond - 148 acres - became a legacy problem. Over €11 million has since been spent on rehabilitation. Mining records in the Silvermines area run from 1289 to 1993: 700 years in the same hills.
