Skara Brae Neolithic Village & Visitor Centre

The Neolithic village of Skara Brae is located near the white beach of Skaill Bay. Uncovered by a storm in 1850, the site provides a remarkable insight into life on the Orkney Islands some 5,000 years ago.
Visitors can get a vivid impression of the reality of a prehistoric settlement and see old houses equipped with stone beds, dressers and chairs. A replica construction allows visitors to fully understand the interior of a prehistoric house.
An informative visitor center offers touchscreen presentations, fact-finding quizzes for kids and adults, and a chance to see artifacts discovered during archaeological digs in the 1970s.
There is also a café (which may have limited hours during the winter) and a gift shop selling locally made souvenirs and crafts.
