Tandragee

Overlooking the town is Tandragee Castle. It was originally the seat of the chief of the O'Hanlon clan, who was Lord of Orior. Because some of the O'Hanlons took part in the Nine Years' War, the castle and surrounding territory were confiscated from the O'Hanlons and granted to Oliver St John and his heirs. Tandragee Castle was rebuilt in about 1837, after having previously been destroyed during the Irish Rebellion of 1641, for George Montagu, 6th Duke of Manchester. Its grounds have been home to the Tayto potato-crisp factory since 1956, after being bought by businessman Thomas Hutchinson.

In February 1973, a confrontation occurred between three gunmen and British soldiers at the Tandragee power station, resulting in one of the gunmen being hit. In 2000, Tandragee was scene of the Murders of Andrew Robb and David McIlwaine, two teenaged local Protestants who were unaffiliated with any paramilitary organization, by three members of the UVF Mid-Ulster Brigade and as part of an ongoing Loyalist feud between the UVF and LVF.
