Barton on Sea (often hyphenated as Barton-on-Sea) is a coastal village situated in Hampshire, England. As a settlement, Barton has a history dating back to Anglo-Saxon times, although the modern village was largely built in the 20th century. It is effectively a suburb of New Milton. Barton is notable for the many fossils to be found in the Barton geological beds in the cliffs, as well as for the significant sea defences built to defend the cliffs against coastal erosion.
The area of Barton has been populated since prehistoric times. A number of bronze age funerary urns were uncovered in Barton during the early 20th century, although most of them have been lost or destroyed. While Barton is a common English place-name, the etymology of Barton-on-Sea is unique. It means Beorma's Farm, and appears twice in the Domesday Book, as Bermintune and as Burmintune.Roger de Montgomerie, 1st Earl of Shrewsbury, and friend of William the Conqueror, held both Barton manors in 1086.
