Lining the northern banks of the river Suir in County Tipperary are a series of tower houses built in the 15^th and 16^th centuries. That above is Dove Hill (or Duff Hill), originally built on land under the control of the O’Mores. In 1542 it was garrisoned by Sir Thomas Butler of Cahir, but a century later was noted in the Civil Survey as being ‘a small castle wanting repaire’. The description remains apposite. A few miles to the west stands Poulakerry, another building once associated with the Butlers. Unlike Dove Hill, it has been restored and is now occupied.
