On 4 June 1817 - the same year Jane Austen died and Britain was struggling to recover from twenty years of Napoleonic war - a light came on at the entrance to Cork Harbour, and it has never properly gone off since. The original tower was deemed too small almost immediately, and replaced in 1835 by the present 49-foot stone column. The second-order Fresnel lens installed in 1876 is still there. The lighthouse has been converted from oil lamps to electricity to LED, has watched the Lusitania survivors come in past it in 1915, has heard depth charges drop on UC-42 in 1917 just off its rocks, and has guided every ship that ever entered Cork Harbour for two centuries. In 2017, for its bicentenary, 1,500 people climbed its narrow stairs in a single day.

In 1876 the ...

Roche's Point Lighthouse: The Light's Character

Sat, 23 May 2026 00:00:00 GMT

Photo credit Glcork, CC BY-SA 3.0. Every lighthouse has a 'character' - a unique rhythm of flashes and timings that lets mariners identify it at night. Roche's Point originally flashed an 'occulting 20s' character - on for 15 seconds, off for 5, repeating. On 15 August 1993 the character was changed to Fl WR 3s - ...

It was replaced on 1 December 1898 by a siren that could be heard further. In 1949 came a diaphone - the great deep two-tone foghorn invented in Canada and beloved of coastal towns from Ne...

Jim Power was the last lighthouse keeper at Roche's Point before automation, and after the keepers' service ended he stayed on as the lighthouse attendant - one man with a key, looking after the equipment that now ran itself. On 4 June 2017, exactly 200 years after the light firs...
