About the town » Portishead, North Somerset, England, Great Britain

Portishead /pɔːrtɪsˈhɛd/ is a coastal town on the Severn Estuary, close to Bristol, but within the unitary authority of North Somerset, which falls within the ceremonial county of Somerset, England. It has a population of around 22,000, an increase of over 3,000 since the 2001 census, with a growth rate considerably in excess of surrounding towns. By the time of the 2011 Census the population had increased to approximately 24,000. Portishead has a long history as a fishing port. It expanded rapidly during the early 19th century around the docks, with supporting transport infrastructure. A power station and chemical works were added in the 20th century, but the dock and industrial facilities have since closed and been redeveloped into a marina and residential areas. Portishead was also the telephone control centre used by British Telecom (BT) for non-direct dialled calls to maritime vessels, a service known as Portishead Radio. The town's population is expanding, and Portishead is now primarily a dormitory town for Bristol and its environs, although a range of service industries has grown up. The headquarters of Avon and Somerset Constabulary are in Portishead.
