Westray (ˈwɛstriː, Westree) is one of the Orkney Islands in Scotland, with a usual resident population of just under 600 people. Its main village is Pierowall, with a heritage centre, the 15th-century Lady Kirk church and pedestrian ferry service to nearby Papa Westray island. Westray has a number of archeological sites dating from 3500 BC, and remains of several Norse-Viking settlements. The spectacular sea cliffs around Noup Head are home to thousands of seabirds. Westray has an area of , making it the sixth largest of the Orkney Islands. The underlying geology is Rousay-type Middle Old Red Sandstone, the flagstones of which make excellent building materials. There is very little peat and the soil is noted for its fertility. At the time of the earliest known settlements, c. 3500 BC, in Westray and neighbouring Papa Westray, it is believed that the two islands were joined. A Neolithic and Bronze Age site at the Links of Noltland is in the care of Historic Scotland. The site is threatened by the rapid erosion of the overlying sand dunes. Ongoing excavations have revealed over 30 buildings of Neolithic and Bronze Age date, the earliest of which overlaps in use with the Knap of Howar on the neighbouring island of Papa Westray (known as Papay to the locals), the oldest standing structure in NW Europe. The Westray Wife, 4 cm carved Neolithic figurine was discovered on the Noltland dig in 2009; this is the oldest carving of a human found in the British Isles. In 2010 some local businesses reported a 45% increase in turnover since the discovery of the figurine. Since then, four further figurines have been found, together with a wealth of other artefacts (carved stone ball, decorated grooved ware pottery, numerous carved bone objects and beads etc.). In 2015, a substantial subterranean building dating from the Bronze Age was uncovered; this was very well preserved and is interpreted as a sauna. The excavations won 'Best Rescue Dig' of the year in the prestigious 2014 Current Archaeology awards.
