Newnham or Newnham on Severn is a village in west Gloucestershire, England. It lies in the Royal Woodland of Dean, on the west bank of the River Severn, around 10 miles south-west of Gloucester and 3 miles southeast of Cinderford. It gets on the A48 road between Gloucester and Chepstow, Monmouthshire, Wales. The village has a parish council. A parish church was developed in the 14th century (although there had actually been a church of simplicity since 1018), as well as in 1366 a brand-new church building was improved the high ground of the town as the old one encountered disintegration from the river. The new structure has itself been damaged by a gunpowder surge in 1644 throughout the English Civil War as well as a fire in 1881, but is still being used. Because of Newnham's area on the Severn, the Old Romans constructed three roads through the area, where they forded the river. The Anglo-Saxons established a permanent negotiation, the Normans constructed a motte-and-bailey fortification for defence, as well as in medieval times it became a significant port with links around Great Britain and Ireland. In 1171, Henry II of England presented an invasion of Ireland from Newnham. One account declared that he set sail with 400 ships as well as 5,000 men, which recommends its significance as a port. For a time Newnham was the most effective Gloucestershire town west of the Severn. Its function as a port as well as trading hub decreased, nonetheless, quickly with the 1827 opening of the Gloucester as well as Sharpness Canal. In 1810, an early effort at a Severn tunnel started building and construction just south of Newnham. Job was abandoned after flooding in 1812. The civil parish becomes part of Newnham as well as Westbury selecting ward. This ward begins in the north at Westbury-on-Severn and afterwards complies with the River Severn to Newnham. The total population of the ward taken at the 2011 census was 3,088.
