Lesser Spotted Ulster: Newtownstewart

Joe Mahon returns with another quirky travel series in which he explores the beautiful, but often overlooked, nooks and crannies of the Ulster countryside and exchanges banter with the local citizens. This week finds Joe trying to sort out the name of a certain river in Co. Tyrone on which stands the town of Newtownstewart, and exploring an extraordinary legacy of castles, raths and dolmens in the countryside around.
