The Electric Brae, known locally as Croy Brae, is an antigravity hill on the A719, between Drumshrang and Knoweside, on the south-west coast of Scotland.[a]Brae is a Lowland Scots word for the slope or brow of a hill. It is an optical illusion caused by the layout of the land through which it runs, making it seem as if a freewheeling vehicle is drawn uphill by some mysterious “magnetic” attraction. A key element of the illusion at the Electric Brae appears to be a misperception of the horizon by the observer, caused in part by the hills in the background.
Similar antigravity hills, also known as spook hills or magnetic hills, are found across the world. Most are relatively narrow, short stretches of road, 50–90 metres in length, set in a hilly landscape with no surrounding buildings; the Electric Brae is relatively long, at about a quarter of a mile (400 m) in length.
