County Tyrone in the province of Ulster is one of the six counties that make up Northern Ireland. It covers an area of 3,155 square kilometres and has a population of about 177,986.
It is the largest of the six counties in Northern Ireland although historically the lands were much larger, stretching as far as the River Foyle. The county town and settlement with the largest population is Omagh.
The county takes its name from the town of Tír Eoghain, the Irish phrase for the land of Eoghan. This was a large Gaelic kingdom ruled by the O’Neills until the 17th century.
