Place & story
A light beside the pier
Blacksod’s light was first shown on 30 June 1866. The site selected beside Termon pier differed from an earlier proposal for the peninsula’s southernmost point. John Swan Sloane prepared the plans, and Bryan Carey built the lighthouse. The Board of Trade required changes to the proposed square lantern, producing the distinctive combination of a square granite tower and a glazed seaward lantern. [2]
Granite carried to the quay
The local granite quarries had their own narrow-gauge tramway to the harbour. Irish Lights records describe loaded wagons hauled over the hill by a winch and lowered towards the quay. Negotiations over access repeatedly involved the lighthouse land. In the late nineteenth and early twentieth centuries, the railway passed through the shore-dwelling compound used by keepers of the offshore Blackrock light. [2]
Maureen Flavin and the D-Day observations
Maureen Flavin arrived from Knockanure in 1941 to work in Blacksod’s post office and weather station. On 3 June 1944, its reports of falling pressure and strong winds helped Allied forecasters recognise conditions unsuitable for the planned Normandy invasion. Improving observations followed on 4 June, contributing to the decision to land on 6 June. She later married lighthouse keeper Ted Sweeney; they learned the wartime significance of their observations only in 1956. [3]
