Paired towers
Study the two towers from the permitted viewpoint. Their gatehouse-like appearance is striking, but the heritage interpretation explains a function closer to a residential tower house than a simple gateway.

Harry Avery's Castle
Harry Avery’s Castle is a ruined medieval stronghold near Newtownstewart, distinguished by its paired towers and raised enclosure. Its appearance can suggest a conventional gatehouse, but the surviving building had a more complex residential role. A short ground-level visit offers a useful introduction to an unusual Gaelic castle and its commanding setting.
From research
Is this worth your time?
Choose it if you enjoy comparing castle designs rather than expecting a complete interior route. Look at the towers first, then relate them to the mound and enclosure behind. The structure is distinct from Newtownstewart Castle in the town, which belongs to a later historical period and has different access arrangements.
Know before you book: Free outdoor monument access, subject to temporary restrictions. Stay on authorised ground and do not climb ruined walls or closed parts of the structure.
Place highlights
What you will actually see
Raised enclosure
Look at the mound behind the towers and the surviving outline of the enclosure. The relationship between the front structure and elevated space helps make sense of an otherwise puzzling plan.
Building details
Where visible from the public route, look for the doorway fittings and other practical details. Small features can say as much about use and defence as the overall silhouette.
The story behind the visit
The story behind the place
The castle is thought to date from around 1320 and is associated with an O’Neill chieftain. Its familiar name recalls Henry Aimbreidh O’Neill, known as Harry Avery, who died in 1392. The Department for Communities highlights its unusual form and the comparative rarity of stone castles built by Irish chieftains of that period. Source ↗
The paired towers look like a gatehouse, yet the building functioned more like a medieval tower house. An elevated route linked it with the enclosure behind, where the curtain wall now survives mainly as foundations. That distinction makes the ruin rewarding to examine slowly. Rather than reconstructing a complete fortress in your mind at first glance, compare the surviving features with the plan and allow the unusual arrangement to explain itself. Reading the mound and towers together helps prevent a familiar architectural label from replacing the more unusual story told by the surviving plan. Source ↗
