Belnahua

Belnahua is one of the Slate Islands, in the Firth of Lorn in Scotland, known for its deserted slate quarries. The bedrock that underpins its human history is part of the Scarba Conglomerate Formation and its value has been on record since the 16th century. Likely uninhabited before commercial quarrying commenced, under the control of the Stevenson family during the 19th century the population expanded to over 150 before the island was abandoned again in 1914.

Living on a remote island in the 19th century came with significant hardships and the lives of the quarry workers have been described in unflattering terms by modern commentators, one describing them as in effect "slaves". Today, the ruined buildings and abandoned machinery lie amidst the water filled quarries and are home only to wildlife. There are very strong tidal streams in the area and this a potentially hazardous location for shipping. In 1936 the cargo vessel Helēna Faulbaums was wrecked on the island, with the loss of 15 lives.
