What is recorded here

Indicated is a 370m V-shaped stone causeway buried beneath Shannon silts beside Clonmoney, still visible on Admiralty charts though its purpose remains unknown. It may have linked Inishcronan Point to Saint’s Island, trapped fish, drained a mudflat or turned tidal water into mill power. The sea took back whatever hands built it, leaving only a chart line and a shape the marsh remembers.

On the N bank of the Shannon estuary adjacent to Clonmoney townland. Described by O’Sullivan (2001, 304) as a ‘large V-shaped stone wall or causeway, c. 370m long, buried under silts between Inishcronan Point and Saint’s Island. The feature is depicted on the OS 6” second edition map Clare No. 61 (it is not marked on first edition) and Admiralty charts of the Shannon estuary (No. 1540). Function unknown; may be causeway to island, failed mudflat reclamation feature, fishtrap or tidal watermill. Observed from saltmarsh after completion of survey, March 1999.' This feature is of unknown date. (O'Sullivan 2001, 304, Inishcronan rocks 1) Compiled by: Mary Tunney Date of upload: 27 August 2019
