Harry Avery’s Castle is located on the hill behind the village of Newtownstewart in county Tyrone. It is named after Harry Avery O’Neill, the 14th century local chieftain. The structure is considered unusual because Irish chieftain’s of the time rarely built stone castles and this one copied many elements from Norman Castles. It was built at the end of the Norman period of domination in Ireland in the year 1320 and it’s two towers look like gatehouses similar in style to those of Carrickfergus Castle. In reality they served a similar function to an Irish medieval tower house. Inside is a large mound which forms the courtyard, a draw bar slot on the main door and a latrine chute. The castle was also surrounded by a curtain wall, of which only the foundations remain today and would have many wooden buildings such as kitchens and stables in the courtyard.
