Port Grenaugh, Purt ny Ceabagh Promontory Fort
Period: Iron Age - Early Medieval
NGR Easting: 231940
NGR Northing: 470340
Description: Iron Age defended promontory. This headland stands higher than the adjacent land, a natural defence which is augmented by a bank and ditch protecting the interior of the promontory. The bank still rises 2.5m from the bottom of the ditch, despite the former no doubt being eroded and the latter partially filled with debris. The inner height of the bank is 1.3m. The whole site is covered by vegetation and the interior of the promontory shows no trace of internal structures, nor of a peripheral bank.
The site lies just 250m from the defended promontory of Cronk ny Merriu (1068).
