Gallibury Hump is the most conspicuous of the barrows on Brightstone Down – in fact, at three metres high it’s probably the biggest round barrow on the Isle of Wight. According to Dyer’s ‘Southern England’ it’s largely composed of flints.
Sir John Oglander described it in 1640 as being “where ye ffrench weare buried, being overcome theyre in a battayle” – hence neatly explaining its purpose and name in one.
Dyer however backs the explanation that a gallows probably stood on it.
