Dubh Artach Lighthouse

Dubh Artach is a small, dark basalt skerry 29 kilometres west of Colonsay and 24 kilometres south-west of Mull in the Inner Hebrides. The rock rises only eleven metres above the sea but is surrounded by a deep Atlantic valley that stretches 130 kilometres west. Waves here often reach twenty-eight metres, making it one of the stormiest places on earth. The lighthouse tower, designed by Thomas Stevenson, stands 44 metres tall on this isolated outcrop. A shore station was built on Erraid, fourteen kilometres away, to house workers and store granite blocks. The need for the light became clear after repeated wrecks, including thirty-three lives lost on the steamer Bussorah in 1863. Pressure from insurers and the Admiralty finally overcame doubts, and construction began in 1867. Despite iron barracks being swept by seas 23 metres above normal level, the team completed the foundation and lower tower by 1869. The solid base alone weighs 1,840 tonnes and rises more than 20 metres above the waves. Visitors today see a 31-metre stone tower rising from the black rock, its seventy-seven courses of masonry still intact. The lantern, fog bell and original paraffin light remain in place. The shore station on Erraid, once a hive of quarrying and stonemasonry, now serves as a quiet reminder of the human endeavour that tamed this deadly reef. The contrast between the barren skerry and the carefully fitted granite blocks tells the story of courage and skill.
