THE 1955 Kelvin Diesel engines – used to create the compressed air to run the Fog Horn at the Mull of Galloway Lighthouse – are now operational again after 30 years.

The Fog Horn, which is located 100 feet below the lighthouse was last sounded in 1987, a year before the Lighthouse became fully automatic.

On Sunday, April 30, there will be a ‘Grand Switch On’ and demonstration of the engines.

This memorable event will take place at 1.30pm with a piper welcoming you to Scotland’s most Southerly Point.

This will be followed by the switch on at 2pm by John Ross, Commissioner of Northern Lighthouse Board.

George McDermid, Former Lighthouse Keeper, will be on hand to chat to visitors and answer any questions about the engines and the role of the keeper in the operation of the Fog Horn.

The ladies from Kirkmaiden Church will be serving tea, coffee, scones and fruit cake and all proceeds will go towards church funds. The event is sponsored by Portpatrick Brewery who have named one of their real ales after the Mull of Galloway Fog Horn.

The event is free to attend and everyone is welcome. It’s also a great opportunity to celebrate Lighthouse Heritage as part of the 2017 Visit Scotland Year of History, Heritage and Archaeology

The Lighthouse Exhibition and tours of the Lighthouse open on Saturday (8th).
