Brough of Birsay

The oddity, explained

Why is Brough of Birsay unusual?

Brough of Birsay appears here because the approved source classifies it as odd boundaries. The source describes it as an uninhabited tidal island off the north-west coast of The Mainland of Orkney, Scotland. Heritage Atlas treats that specific classification-and-description combination as the oddity; the score is a comparative discovery signal, not proof of mystery or the supernatural.

Evidence and further exploration

The coordinate, category and description remain tied to the cited source. Comparative oddness helps discovery; it does not add facts that the source does not provide.
