2,000 BC to 1628
The three stones and the castle
The village is named for a megalithic tomb - Trí Leac, three flagstones. The three pillar stones are still standing near the site of Trillick Castle, the doorway between them aligned to face the rising sun. They date to the Beaker period, the early Bronze Age, around 2,000 BC. An early Christian foundation followed at Trelic Mór; the Annals of the Four Masters record a Bishop of Trelic dying in 813 AD. Then the O'Neills held the territory, fighting the Maguires at nearby Dreigh Hill in 1379 in a battle that fixed the Tyrone-Fermanagh boundary. Captain James Mervyn, a Plantation undertaker, began building his castle on the site in 1620 and finished it in 1628. It stood occupied until sometime in the early 1800s. The three stones are older than everything that came after them and are still there.
Founded 1932
Trillick St Macartan's and nine championships
The West Tyrone GAA Board was established on 29 October 1931. Trillick St Macartan's was among the first clubs formed under it, in 1932. Their first county senior championship came in 1937, followed by League titles in 1937, 1938 and 1939 in a run of early dominance. Then 1974 - when they reached the Ulster Senior Club Championship final - 1975, 1980, 1983, 1986. The modern era: 2015, 2019, 2023. Nine titles verified. For context: Tyrone fields some of the strongest club football in Ulster, and most of those clubs come from towns rather than villages of a few hundred people. Mattie Donnelly, an All-Ireland senior medalist with Tyrone in 2021, has been the club's most prominent player in recent years. That Trillick competes and wins is the defining fact of the place.
