Armagh (from Irish Ard Mhacha, meaning "Macha's height") is the county town of County Armagh in Northern Ireland, as well as a civil parish. It is the ecclesiastical capital of Ireland – the seat of the Archbishops of Armagh, the Primates of All Ireland for both the Roman Catholic Church and the Church of Ireland. In ancient times, it and nearby Navan Fort (Eamhain Mhacha) was one of the great royal capitals of pagan Gaelic Ireland. Today it is home to two cathedrals and the Armagh Observatory.
Although classed as a medium-sized town, Armagh was given city status in 1994 and Lord Mayoralty status in 2012, both by Queen Elizabeth II. Its population of 15,000 makes it the least-populated city in both Northern Ireland and on the island of Ireland, and the fourth smallest in the United Kingdom.From Wikipedia - click for full entry
