Scalpay is an island in the Outer Hebrides of Scotland. Scalpay is around 4 kilometres (2.5 miles) long as well as rises to an elevation of 104 metres (341 feet) at Beinn Scorabhaig. The area of Scalpay is 653 hectares (2.52 sq mi). The primary settlement on the island is at the north, near the bridge, clustered around An Acairseid a Tuath (North Harbour). The island is peppered with small lochans. The biggest of these is Loch an Duin (Loch of the Fort) which has a little island in it, with the remains of the fort still noticeable. Eilean Glas, a small peninsula on Scalpay's eastern coast, is home to the very first lighthouse to be built in the Outer Hebrides. Scalpay's local neighbor, Harris, is simply 300 metres (980 feet) away across the narrows of Caolas Scalpaigh. In 1997, a bridge from Harris to Scalpay was constructed, replacing a ferry service. In 2001, the island had 322 people, whose primary employment was fish farming as well as prawn fishing. By 2011 the population had actually decreased by 9% to 291 whilst during the exact same period Scottish island populations in its entirety grew by 4% to 103,702.
