This rugged landscape, measuring roughly 700 metres north to south and varying between 50 and 220 metres east to west, represents the highest point of the island, rising dramatically from the Atlantic Ocean. The area contains an extraordinary collection of ancient defensive structures, hut circles, and enclosures that tell the story of centuries of human habitation on this remote outpost off the Donegal coast.

The southern section of the peninsula is accessed via a narrow isthmus that forms a natural defensive ditch, reinforced by the remnants of a stone wall approximately 40 metres long. Historical records from the Civil Survey of 1654-56 mention a 'Little Castle' in this vicinity, though no visible traces of this structure remain today. Further east, the defences become more elaborate, featuring a 105-metre-long earthen and stone bank with an accompanying fosse, alongside various enclosures that may have served as dwellings or storage areas. The most impressive fortification, known locally as 'Balor's Fort', consists of four massive earthen banks with three intervening ditches, strategically positioned across another narrow isthmus. These formidable defences protect an area containing at least twenty hut circles, built directly on the rocky surface before or during the early development of the island's turf layer.

The easternmost section of the archaeological complex extends onto a precipitous arm of land dominated by Tor-more, an almost inaccessible blade of rock jutting into the sea. Access to the level area at its base is restricted by a rock-cut fosse measuring 1.5 metres deep, with evidence of an internal bank on its eastern side. Near the cliff edge stands a collapsed stone enclosure, testament to the determination of Tory's ancient inhabitants to utilise every available space on this windswept island. While local tradition offers no explanation for these structures' original purpose, their positioning and construction suggest a community that valued defence and adapted ingeniously to one of Ireland's most challenging coastal environments.
