Papa Stour is one of the Shetland Islands in Scotland, with a population of under fifteen people, some of whom immigrated after an appeal for residents in the 1970s. Located to the west of mainland Shetland and with an area of 828 hectares (3.2 square miles), Papa Stour is the eighth largest island in Shetland. Erosion of the soft volcanic rocks by the sea has created an extraordinary variety of caves, stacks, arches, blowholes, and cliffs. The island and its surrounding seas harbour diverse populations of wildlife. The west side of the island is a Site of Special Scientific Interest and the seas around the island are a Special Area of Conservation.
The island has several Neolithic burial chamber sites, as well as the remains of Duke Hakon's 13th-century house dating from the Norse occupation of the island. The population reached 380 or more in the nineteenth century, when a fishing station was opened at Crabbaberry in West Voe. Subsequently, there was a steady decline in population.
Today the main settlement on the island is Biggings, just to the east of which is Housa Voe from where the Snolda ferry arrives from its base at West Burrafirth on the Shetland Mainland. Crofting, especially sheep rearing, is the mainstay of island life.
