History
Blacksod Lighthouse
A square granite lighthouse built in 1864 on the southern tip of the Mullet. On 3 June 1944, keeper Ted Sweeney's hourly weather report — recording a falling barometer over the North Atlantic — was relayed to General Eisenhower in England. Eisenhower postponed the Normandy landings by 24 hours. A small museum in the keeper's quarters tells that story.
Good to know · Off the R313 at the southern end of the peninsula. Museum seasonal — check ahead.
