Halidon Hill is a summit, about 2 miles (3 km) west of the centre of Berwick-upon-Tweed, on the border of England and Scotland. It reaches 600 feet (180 m) high. The name of the hill indicates that it once had a fortification on its top. At the Battle of Halidon Hill in 1333, Edward III of England used longbowmen on the heights of the hill to defeat the Scottish army led by Archibald the "Tyneman" Douglas, Regent of Scotland.
