The National Monuments Service's description

Located c. 70m from the W shore of Lough Rinn (dims c. 3.8km N-S; c. 200-400m E-W) close to its N end. This is an overgrown oval island (dims 15m N-S; 11m E-W; H 1.15m) surrounded by a band (Wth 3-4m) of timber stakes and planks lying intertwined along the water's edge. This is most clearly visible at NE and E. The centre of the island has been augmented with stone, while a crude stone pier can be seen under the water at E. A programme of radiocarbon dating undertaken by the Discovery Programme produced a date of 985 +- 30 BP (AD 990-1154) from wood taken from the crannog (O’Conor and Fredengren 2019, 91).

The above description is derived from 'The Archaeological Inventory of County Leitrim' compiled by Michael J. Moore (Dublin: Stationery Office, 2003). In certain instances the entries have been revised and updated in the light of recent research.
