Blacksod Lighthouse (Gaelic: Fód Dubh) is a lighthouse at the southern end of the Mullet Peninsula, Erris, County Mayo, at the entrance to Blacksod Bay.[1] It is made of local granite blocks, which are believed to have come from Termon Hill, a nearby isolated outcrop of high-quality granite.[2]
The keeper's house is a two-storey square building. It is occupied by a resident lighthouse keeper who is also responsible for Blackrock Lighthouse. Blacksod is of unusual design for a lighthouse, being an unpainted square block of a building with only a small conical lantern section on top, which is painted white.
The need for a lighthouse at the southern extremity of the Mullet peninsula was first mentioned in 1841 when all Ireland was part of the United Kingdom. A Lieutenant Nugent, an officer in the British Coastguard stationed at Belmullet, requested in a letter that a lighthouse be placed on Blackrock Island. But Inspector George Halpin, a senior civil engineer responsible for building Irish lighthouses, recommended to the Dublin Ballast Board (the predecessor to the Commissioners of Irish Lights) that a sea light should not be built on Blackrock Island but instead be sited on Blacksod Point – the southernmost point of the Mullet Peninsula – to guide vessels into Blacksod Bay.
The lighthouse at Blacksod Point was completed in 1864; the work had been funded by Bryan Carey, one of the leading merchants in Belmullet at that time.[3] [4] The light was first illuminated on 30 June 1866, and showed a fixed light with a red sensor over Ardelly Point. At first, the relief keeper ashore from Blackrock looked after the light, but on 1 November 1933, Edward (Ted) Sweeney was appointed as attendant.
Weather observations in June 1944 by the Blacksod lighthousekeepers caused the Normandy landings to be postponed. While remaining neutral during World War II, Ireland continued to supply weather reports to Britain under an agreement in place since independence.[5] D-Day had been scheduled to commence on 5 June 1944, but a report from Maureen and Ted Sweeney (Blacksod's lighthousekeepers) of approaching bad weather fronts caused General Eisenhower to delay the invasion until 6 June 1944, when conditions were more favourable.[6] [7] [8]
In addition to being attendant lighthouse keepers, the Sweeney family were also local postmasters. During the late 1960s, the old cottage where the post office was located was pulled down and a new bungalow, with a post office attached, was planned. While this was being built, between 1969 and 1972, with the permission of both Irish Lights and the Department of Posts and Telegraphs, the Blacksod Post Office was accommodated in one of the rooms under the lighthouse tower, marking the first and only time a post office formed part of a working lighthouse.
Towards the end of 1969, Blacksod became the helicopter base for Eagle Island and Blackrock Island lighthouses. As of 1993, the helipad was in use as the base for the monthly visits of the attendant keepers to the automated lights on the two islands.
The house at Blacksod was badly damaged in 1989 by a rogue wave. It was repaired and used by the Commissioners of Irish Lights and the Irish Coast Guard as a refuelling station for helicopters. The lighthouse, which used to be a family home, was later opened as a visitor centre, and offers some guided tours.[9]
The keeper for Blacksod Lighthouse is also responsible for Blackrock Lighthouse at Blackrock Island. Located 12 miles west of Blacksod Bay, the lighthouse on Blackrock is automated and accessible only by helicopter. On 14 March 2017, four Irish Coast Guard personnel were killed in a crash off Blackrock Lighthouse when it was understood they were seeking to refuel at Blacksod lighthouse.
