Round Tower at Tory Island, Co. Donegal

Round Towers
On Ireland's most isolated inhabited island, medieval monks built a tower from pink granite beach stones and crushed shells, creating a lighthouse of faith that has weathered Atlantic storms for over a millennium.
Standing in the West Town settlement on the south side of remote Tory Island, this round tower forms part of one of Ireland's most isolated early ecclesiastical complexes. The site has deep historical roots; literary references to Tory's ecclesiastical importance begin in the 7th century and continue throughout the medieval period, though today only fragments remain of what the Civil Survey of 1654-56 described as "five churches almost ruined."
The tower itself rises 12.8 meters high with a circumference of 15.7 meters at its base. Built from distinctive pinkish granite beach stones mortared with shell lime—materials that speak to the island's maritime environment; it represents the resourcefulness of medieval builders working in Ireland's most remote locations.
The structure shows the typical damage pattern of many round towers: it's partially breached on the west side while remaining intact on the east up to the cornice line, above which a small portion of the original cap still survives. The doorway, positioned 2.64 meters above ground level and facing east-southeast, follows traditional round tower design with its rounded head. It measures 1.65 meters high and 61 centimeters wide, with a mortice for door fastenings still visible on the north jamb.
Only one window survives below the cornice line, positioned above the doorway. The interior originally had three floors, with the top level formed by stone vaulting—a sophisticated architectural feature that demonstrates the tower's importance and the skill of its builders.
The Office of Public Works carried out repairs in the 1970s, helping to stabilise this remarkable survivor from Ireland's early Christian period. The tower's location on Tory Island, one of Ireland's most isolated inhabited islands, makes it a particularly poignant reminder of how far the influence of early Irish monasticism extended, reaching even the most remote corners of the Atlantic coast.

Good to Know
Getting to Tory Island requires planning, as ferry services operate from Bunbeg and Magheroarty on the mainland, weather permitting. Services can be cancelled at short notice due to rough seas, so check conditions before travelling. There's no formal car parking near the tower; simply leave vehicles respectfully in West Town where the ferry docks. The walk to the tower is short. The site is always accessible, though the tower interior is not open to visitors. Bring layers and waterproofs, as Atlantic weather changes quickly. Consider combining your visit with the island's other attractions, including Balor's Fort and the lighthouse, as return ferries may not run as frequently outside summer months.
