This major lighthouse was built (as part of an extensive programme of construction works around northern Scotland) by D A Stevenson, and was first lit in 1896. It suffered aerial attack in 1941 and was administered as a shore station until 1961, being a rock station thereafter. The light was electrified in 1972, using a sealed-beam system with a maximum power of 1,100,000 cp; it was automated in 1996.
This light succeeded an unmanned minor light of 1890, which was itself of significance as one of the first two around Scotland to use 'scintillating' lights of the Trotter-Lidberg type, with lythene (petroleum spirit) as fuel. The location of this structure is unknown but it may have occupied the same site.
