Portchester  Portchester is a locality and suburb northwest of Portsmouth, England. It is part of the borough of Fareham in Hampshire. Once a small village, Portchester is now a busy part of the expanding conurbation between Portsmouth and Southampton on the A27 main thoroughfare. Its population according to the 2011 United Kingdom census was 17,789 residents. Portchester is derived from its former Latin name Portus Adurni and the Old English suffix "ceaster" ("fort; fortified town"), itself derived from the Latin word “castrum.” The fort of Portus Adurni is considered the best-preserved Roman fort north of the Alps. It is sometimes identified as the "Caer Peris" listed by the 9th-century "History of the Britons" as among the 28 cities of Britain. The medieval Portchester Castle was built within the Roman fort. As well as the castle, its parish church  is listed as a Grade I protected building. There are also many historic houses in Castle Street.
