Portswood is a suburb and Electoral Ward of Southampton, England. The suburb lies to the north-north-east of the city centre and is bounded by (clockwise from west) Freemantle, Highfield, Swaythling, St. Denys and Bevois Valley. Portswood Ward comprises Portswood, Highfield and St. Denys, and had a population of 14,831 at the 2011 Census. It is a largely residential area adjacent to the main campus of the University of Southampton, and as such more than a quarter of residents are students. The Manor of Portswood, which originally included the modern-day Bevois Town, Swaythling, St Denys and Highfield, was first named in a charter dating from 1045. The name Portswood comes from the Old English Porteswuda, meaning "wood of the town". The manor was granted to St. Denys Priory by Richard I in 1189, and it remained under their ownership until the Dissolution of the Monasteries by Henry VIII in 1536. The land, and the title Lord of the Manor, were purchased by Francis Dawtrey in 1538, and passed through several hands before being bought by Giles Stibbert in 1771. Stibbert, Lieutenant-General with the East India Company and later Commander-in-Chief of India, built the first Portswood House on the estate to the design of a Mr. Crunden. The house, which stood in the area now bounded by Spring Crescent and Lawn Road, was demolished in 1852 to make way for more housing, and the name Portswood House transferred to the nearby Portswood Lodge. The estate was gradually sold for development, and the second Portswood House was demolished in 1923, allowing the whole estate to be sold by 1928. In 1871 an attempt by the Southampton board of health to improve the local sewage system was opposed over concerns about higher taxes. Improvements were eventually begun in 1875. Prior to 1894, Portswood was a tithing in the parish of South Stoneham, a parish more than ten times the size of Portswood Ward today, stretching as far as Eastleigh to the north.
