Although the museum has a wide range of exhibits covering many aspects of Scottish lighthouses from their initial designs to their current maintenance, the most striking parts of the collection are definitely the huge Fresnel lenses that were used to concentrate and direct the light from various lighthouses around the coast of Scotland. Modern lighthouses usually just have really bright lights that flash on and off rather than relying on these structures.
Scotland's lighthouses are all automated now; though the Northern Lighthouse Board does have maintenance crews that check the lights are working, keep the glass clean and so on, they don't have keepers in residence 24/7 any more.
