Plympton is a suburb of the city of Plymouth in Devon, England. It is in origin an ancient stannary town. It was an important trading centre for locally mined tin, and a seaport before the River Plym silted up and trade moved down river to Plymouth and was the seat of Plympton Priory the most significant local landholder for many centuries. Plympton is an amalgamation of several villages, including St Mary's, St Maurice, Colebrook, Woodford, Newnham, and Chaddlewood. Fore Street, the town's main street, is lined with mediaeval buildings, around thirty of which are either Grade II* or Grade II listed. The Grade II* buildings are The Old Rectory, the Guildhall and Tudor Lodge. Toponymy Although the name of the town appears to be derived from its location on the River Plym (compare, for instance, Otterton or Yealmpton), this is not considered to be the case. As J. Brooking Rowe pointed out in 1906, the town is not and never was sited on the river – rather it is sited on the ancient trackway called 'the Ridgeway' from Dartmoor. The earliest surviving documentary reference to the place is as Plymentun in Anglo-Saxon charter S380 dated to around 900 AD, and this name may be derived from the Old English adjective plymen, meaning "growing with plum-trees". So Plympton would have the meaning "Plum-tree farm". Alternatively, Cornish derivations also give ploumenn meaning 'plum' and plo(b)m meaning 'lead' – possibly related to Latin plombum album ( 'British lead') or tin. The local civic association, however, suggests an unsupported alternative derivation from the Celtic Pen-lyn-dun ("fort at the head of a creek"). By the early 13th century, the River Plym was named from a back-formation from this name and nearby Plymstock. This later led to the naming of the fishing port created at the river's mouth (Plymouth, originally named Sutton) when the river estuary silted up too much for the monks to sail up river to Plympton any longer. History Nearby is the Iron Age hill fort of Boringdon Camp. Plympton is listed in the Domesday Book of 1086 as being held by the king (William the Conqueror), with 27 villagers, 12 smallholders and 6 slaves. In the early 12th century Plympton was the site of an important priory founded by William Warelwast. The members were Augustinian canons and the priory soon became the second richest monastic house in Devon (after Tavistock). The gatehouse
