caption_attribution_description: English: Blackrock Bridge This is an old disused railway bridge which used to carry the line from Omagh to Derry, over the river Mourne near Newtownstewart. Despite almost 50years neglect, the bridge is still standing. The road 'snaking' parallel to the river is the main A5 between Newtownstewart and Omagh.
context_page_description: County Tyrone is one of the nine counties of Ulster, one of the six counties of Northern Ireland and one of the thirty-two counties on the island of Ireland. It is no longer used as an administrative division for local government but retains a strong identity in popular culture.
  Adjoined to the south-west shore of Lough Neagh, the county covers an area of 3,263 km² and has a population of about 177,986; its county town is Omagh. The county derives its name and general geographic location from Tír Eoghain, a Gaelic kingdom under the O'Neill dynasty which existed until the 17th century.
context_section_description: With an area of 3,155 square kilometres (1,218 sq mi), Tyrone is the largest county in Northern Ireland. The flat peatlands of East Tyrone border the shoreline of the largest lake in the British Isles, Lough Neagh, rising gradually across to the more mountainous terrain in the west of the county, the area surrounding the Sperrin Mountains, the highest point being Sawel Mountain at a height of 678 m (2,224 ft). The length of the county, from the mouth of the River Blackwater at Lough Neagh to the western point near Carrickaduff hill is 55 miles (89 km). The breadth, from the southern corner, southeast of Fivemiletown, to the northeastern corner near Meenard Mountain is 37.5 miles (60.4 km); giving an area of 1,260 square miles (in 1900). Annaghone lays claim to be the geographical centre of Northern Ireland.
  Tyrone is connected by land to the county of Fermanagh to the southwest; Monaghan to the south; Armagh to the southeast; Londonderry to the north; and Donegal to the west. Across Lough Neagh to the east, it borders County Antrim. It is the eighth largest of Ireland's thirty-two counties by area and tenth largest by population. It is the second largest of Ulster's nine traditional counties by area and fourth largest by population.
