Fastnet Lighthouse – Preservation works underway

Fastnet Lighthouse – Remedial works

Fastnet Lighthouse remedial works underway

Visitors to the Fastnet Lighthouse this summer will notice scaffolding around the lantern area at the top of the tower and all the signs of ongoing works.

Of course we wish all involved every success and that they will emulate the superb safety record of the original builders of this fabulous landmark.

The main purpose of the remedial works is to secure the iron lantern room which sits on top of the stone tower. Over the years the bolts which connect this to the tower have become corroded and it is necessary to replace these to ensure the long term preservation of the structure. As part of this major task other relevant maintenance works will also be carried out.

Environmentally friendly and cost effective.

The original revolving lantern lies on a bed of mercury and in line with current best practice this mercury will be removed and the lantern itself will be replayed by a newer, solar powered version which will have a range of 18 nautical miles. Unfortunately while the new light will no longer have the iconic revolving beam, associate with the Fastnet, it will be a more cost effective and environmentally friendly option, removing the need for regular transport of fuel oil to the lighthouse needed to operate the current generators.

While we are sad to see the loss of the beam we are delighted that the structure is to be secured for future generations and that our mainly daytime visitors will continue to enjoy the Fastnet experience, pretty much unchanged.

This year we are seeing even greater interest in our Fastnet Tours and will do everything possible to ensure that everyone who wants to will get to see the ‘Teardrop of Ireland’ in comfort and safety.
