Castlederg (earlier Caslanadergy, from Irish: Caislean na Deirge, meaning "castle on the Derg") is a village in County Tyrone, Northern Ireland. It lies on the River Derg and is near the border with County Donegal. It stands in the townlands of Castlesessagh and Churchtown, in the historic barony of Omagh West and the civil parish of Urney. The village has a ruined castle and two ancient tombs known as the Druid's Altar and Todd's Den. It had an estimated population of 2,935 people in 2008.
The village hosts some of the district's key events each year, including the Derg Vintage Rally and the traditional Apple Fair which sees the apple growers of County Armagh visit to sell their wares.
Traditionally, Castlederg was a traveller's stop along the ancient pilgrimage route to Station Island on Lough Derg. The town boasts ancient ruins, monastic settlements and, as the stories go, has connections to Davy Crockett and Joe Sheridan, the creator of Irish coffee.
The Troubles 
Castlederg is cited as "the most bombed small town" in Northern Ireland during The Troubles, though this dubious honour was disputed, with nearby Strabane (although Strabane is a much larger town in which district council Castlederg is a part of) also trying to claim the title.
For more information see The Troubles in Castlederg, which includes a list of incidents in Castlederg during the Troubles resulting in two or more fatalities.
Winter of 2010 
Castlederg recorded a Northern Ireland record low temperature of −18.7 °C (−1.7 °F) on the morning of 23 December 2010.
The narrow-gauge Castlederg and Victoria Bridge Tramway was built in 1883, to link the village with the Great Northern Railway (Ireland) at Victoria Bridge. Castlederg railway station opened on 4 July 1884, but was finally closed on 17 April 1933.
