Arvagh (Irish: Ármhach, meaning “Battlefield”) or Arva, is a town in County Cavan, Ireland, on the shores of Garty Lough and overlooked by Bruse Mountain. It is a scenic town situated in the centre of the drumlin belt. It lies on the border of Counties Longford and Leitrim and is famous as the town where the three provinces of Ulster, Leinster and Connacht meet.
The Arva area was settled by Scottish planters in the early 17th century. A story is told that one of them, John Brown, sold the land here for a horse. The Earls of Gosford, the descendants of the man who bought it, developed the town in the early 19th century, building a Market House which is still standing. In 1841 there were four pubs in the town and the monthly fairs were of considerable local trade importance.
Ármhach (meaning “Place of Slaughter”) was brought about because Arvagh is on the borders of 3 counties and provinces, Leitrim, Longford and Fermanagh (Connaght, Leinster and Ulster). The royal families of these counties would battle in Arvagh and as a result many died, Hence “Place of Slaughter”.
