A Change to The Fastnet Lighthouse

Way back in 2014 I wrote about An Carraig Aonair: The Fastnet Rock and I have decided to repost that today, but with some updated information and photographs, because of an upcoming change announced by Irish Lights. Depending on the story, this is either a relatively benign but majorly cost-saving switch to LED lighting, or a change we must be vigilant about to make sure the Fastnet is left “intact and unharmed”.

Irish Lights tells us that structural repairs. . .are necessary to ensure the metal lantern room is properly secured to the granite tower and modernisation of the light source to an energy efficient rotating LED lantern. When these works are completed the outward appearance of Fastnet will be unchanged. The work will improve our environmental impact by significantly reducing the need for diesel and generators and by removing all mercury from the station. The range of the light will reduce from 27 to 18 Nautical miles.”

While this seems like a sensible and inevitable modernisation, with (according to this letter to the Irish Times) a very significant saving of €100,000 per year, those of us who live around Roaringwater Bay want more information: we want to be sure that the change does not negatively impact on the safety of our sailors and fisherfolk, and does not rob us of the iconic flash that is so much part of our lived experience in West Cork. There will be a meeting on Monday (March 5, 2018) at the Schull Sailing Club to discuss it all.

What follows now is the text of my post from June of 2014, lightly edited and with some newer photographs inserted.

Robert has written about our field trip to Cape Clear Island and I can now reveal that the journey also included a thrilling sail around An Charraig Aonair (Karrig Ane-er, The Lone Rock) better known as the Fastnet Rock; or to thousands of emigrants for whom it was the last sight of their home country, Ireland’s Teardrop.

We had been looking forward with great anticipation to visiting the rock close up. We can see it from our home, a far away mystical crag abounding with lore and legend. We have been awestruck by the waves crashing over the lighthouse in winter storms and wondered at the lives of the lightkeepers who once manned that treacherous outpost. We watched through our telescope as enormous yachts rounded the rock in the biennial Fastnet Race last summer, following the progress of the race on a special iPhone app. I have written elsewhere about the awful tragedy of the 1979 race, in which Gerard Butler and his fellow lightkeepers on the Fastnet played a crucial role in monitoring the participating yachts in the mountainous sea conditions. 

The signal station and the first lighthouse, on Cape Clear Island

The Fastnet was built to avoid such tragedies. Its first iteration was in 1818 as a lighthouse tower on a high point on nearby Cape Clear Island, beside the Napoleonic-era signal tower. However, the light was frequently obscured by fog and after the wreck of the Stephen Whitney in 1847 with 92 souls lost, it became clear that the best place for a lighthouse was on the Fastnet Rock. 

The great era of lighthouse building in Ireland got underway in the mid-nineteenth century. The engineering, design and construction expertise necessary to build lighthouses are impressive enough. Add to this the logistics of building on a tiny and inhospitable rock in a heaving sea on the edge of the Atlantic, and the sheer accomplishment of the objective is  staggering. The first attempt, started in 1849, was of steel and needed constant repair.

The first lighthouse on the rock – it was made of steel and didn’t last

It was decided to replace it with a structure of Cornish granite and the current lighthouse first cast its beam over the waters in 1904. Eamon Lankford in his book Fastnet Rock: An Charraig Aonair describes the building process and provides old photographs illustrating how the granite blocks were ‘floated’ and hoisted on to the islet, having been first assembled and tested in Cornwall. The website Digital Irish Lighthouse Experience by Sandra Michler has an animated sequence showing how this was accomplished. it took eight years.

We were fortunate to have Eamon Lankford as one of our guides on our trip to the Fastnet

One of the best accounts of the building of the lighthouse was in a 2008 article in The Economist called Light on a Lonely Rock. The piece gives fascinating details into the dedications and hardships of the builders and calls the lighthouse “a monument of man’s gift to mankind.” I don’t know who wrote it, but it’s a terrific essay.

According to the Irish Lights website, Fastnet is the tallest and widest rock lighthouse tower in Ireland and Great Britain and was a monumental achievement when completed in 1904. Each of the granite stones of the tower is dovetailed into those around it, bonding the structure into a virtual monolith. This webpage also has several excellent photographs of the lighthouse from the air. What all photographs of the rock also reveal is that the lighthouse is a thing of beauty. Tall, slender and elegant and boasting two balconies, it personifies form and function in the most admirable fashion possible. (Take a look, for example, at Dennis Horgan’s website – he’s an acclaimed aerial photographer and his photograph of the lighthouse is probably the most iconic shot of them all.) Today the Fastnet is fully automated but in The Lightkeeper Gerard Butler describes what it was like to live on the rock in fair weather, when he fished and swam from the steps, and foul, when the seas crashed and roared over the lighthouse as it quivered and shook all night.

One of the stories we heard from Eamon concerned  a daring midnight raid on the lighthouse carried out by an IRA ‘Flying Column’ (experts in guerilla warfare) in 1921 during the Irish War of Independence. They were after the explosives used on the Fastnet to power the foghorn. [EDIT: I have some errors here – please see Finbarr O’Driscoll’s correct information about the raiding party in the comments section.] In researching this story further, I found an article in the 1999 Mizen Journal (no longer in print) by Frank Lannin, based on the eyewitness statement of Sean O’Driscoll.*

The Rock, showing the landing platform, steps and store

Here is part of Lannin’s account:

The breeze had freshened and caused the usual swell around the Rock and there was a rise and fall of several feet. The anchor was let out and the boat moved slowly to the landing place. Positioned on the bow was John O’Regan, a rope tied around his waist, a revolver in his pocket and balancing himself with the rise and fall of the boat. He would have to select the right moment to jump on the Rock and catch the iron ring which was fixed to the Rock. He knew where the ring was fixed, but to grasp it in total darkness was a feat that few would attempt. His vast experience as a seaman was now to be put to the test. As a wave was rising he jumped. It was a tense moment. As the wave covered him he grasped the ring with both hands. (It was an occasion for handclapping, but not tonight.) In seconds he had made the boat fast and the rest of the raiding party were landing on the platform. The huge steel door of the lighthouse was not locked. John was first up the spiral stairway leading to the room where the Lightkeeper was on duty. He put up no resistance and as a precaution the wireless was dismantled. Seventeen boxes of gun cotton and three boxes of detonators and primers were loaded on to the “Maire Cait” by means of the lighthouse derrick. in all, the spoils weighed but one ton. The daring mission was accomplished.

The fog signal, together with the light, was an important aid to navigation for ocean going vessels. It was only in 2011 that the Fastnet foghorn was permanently discontinued, as modern navigation equipment rendered it unnecessary. All around the world people are missing the haunting sound of foghorns now, a sound so many of us grew up with. But at least we can see the light from Carraig Aonair every night and count its ‘character’ – one two three four FLASH…one two three four FLASH – and know that it’s doing its part to keep our mariners safe on the seas that roll outside Roaringwater Bay.
