Rattray Head lighthouse was designed by David Alan Stevenson of the famous Stevenson family and was completed in 1895. The unusual design is because there was originally an old style foghorn (removed before automation in 1982) installed at the station and the base housed the equipment for this.
The lighthouse was automated in 1982, the original fresnel lens was removed and replaced with a sealed beam system (similar to an array of car headlamps), the old lens is now displayed in Aberdeen Maritime Museum.
My grandfather knew one of the attendents who used to look after this light after it was automated and I was fortunate to be able to have a look around the lighthouse on a number of occasions. It is possible to walk out to the lighthouse when the tide is very low.
Rattray Head is one of the most lonely and remote places on the North East coast of Scotland.
