A brief history: Bordered by Lough Neagh and counties Down, Louth, Monaghan and Tyrone, County Armagh is located within the province of Ulster and is a part of Northern Ireland. Until the fourth century, Armagh was home to the Ulidians and ruled by the Red Branch, whose seat of power was Navan Fort, near what is today the city of Armagh. Navan Fort was then called Emain Macha, after the goddess Macha, associated with war, horses and sovereignty. Later in the fourth century, the region was invaded by the Clan Colla, who ruled until the 12th century, when the land was divided into a number of baronies.

In the pages of Irish history, Armagh is especially notable for being the seat of St. Patrick, who built Armagh into Ireland’s ecclesiastical capital and established his principal church there. St. Patrick’s Church of Ireland Cathedral, as it is now called, was first founded in the year 445, and has been destroyed and rebuilt 17 times since then. It is also believed to be the burial place of Brian Boru.

A border county, Armagh has a large Catholic population. During the Troubles, it received the nickname Bandit Country.
