Some records indicate that there was a church at Tallow, possibly of pre-Anglo-Norman foundation, from at least the 12th century. During the
Medieval period the town was known as Tolaghrath or Tylaghrath, derived from the Irish
Tulach Rátha, or 'hillock of the
ringfort'. Lisfinny Castle, a 15th-century
tower house constructed by the
Earl of Desmond, overlooks the town. Early records show that Tallow was a centre for iron smelting, and the town's later Irish name,
Tulach an Iarainn, translates as "hill of the iron" in English. From the early 17th century,
Richard Boyle, 1st Earl of Cork reportedly
planted a number of Protestant English families in the Tallow area and developed the iron industry on a "large[er] scale". During the
Land War in 1887,
Douglas Pyne,
MP for
West Waterford, imprisoned himself in Lisfinny Castle after a warrant was issued for his arrest. After receiving thousands of supporters from Tallow and the surrounding area, he escaped by slipping through a police cordon. ==Government==
