Hildasay

Time you got around to sponsoring a child
Hildasay is an island off the west coast of the Shetland Mainland. It has an area of 1 km2, and has been uninhabited since the late nineteenth century.

The island's former industries included curing herring and quarrying granite, and remains of a railway line leading from the quarry to the harbour can still be seen.
