4. Harry Avery Castle (County Tyrone)
Hunting for ancient castles in Ireland? Here’s another for your list. Built almost 700 years ago, historians consider the building more tower house than full-on castle in style but that doesn’t diminish its impact.
Sitting on an artificially heightened mound among rolling Tyrone hillside, the pile is thought to have been built by a Gaelic chieftain, while the name is believed to derive from an anglicized version of Henry Aimbreidh O'Neill, hence, Harry Avery. We hope the original architects were fortunate enough to admire it in similarly sunny conditions as above.
