Bristol is a city, unitary authority area and ceremonial county in South West England, with an estimated population of 433,100 for the unitary authority in 2009, and a surrounding Larger Urban Zone (LUZ) with an estimated 1,006,600 residents, it is England’s sixth, and the United Kingdom’s eighth most populous city, one of the group of English Core Cities and the most populous city in South West England.
Bristol is the largest centre of culture, employment and education in the region. Its prosperity has been linked with the sea since its earliest days. The commercial Port of Bristol was originally in the city centre before being moved to the Severn Estuary at Avonmouth; Royal Portbury Dock is on the western edge of the city boundary. In more recent years the economy has depended on the creative media, electronics and aerospace industries, and the city centre docks have been regenerated as a centre of heritage and culture. There are 34 other populated places on Earth named Bristol, most in the United States, but also in Peru, Canada, Jamaica, Barbados, and Costa Rica, all presumably commemorating the original.
Bristol has 51 Grade I listed buildings, 500 Grade II and over 3,800 Grade II buildings, in a wide variety of architectural styles, ranging from the medieval to the 21st century. In the mid-19th century, Bristol Byzantine, an architectural style unique to the city, was developed, of which several examples have survived. Buildings from most of the architectural periods of the United Kingdom can be seen throughout the city. Surviving elements of the fortified city and castle date back to the medieval era, also some churches dating from the 12th century onwards. Outside the historical city centre there are several large Tudor mansions built for wealthy merchants. Almshouses and public houses of the same period still exist, intermingled with modern development. Several Georgian-era squares were laid out for the enjoyment of the middle class as prosperity increased in the 18th century.
As a major seaport, Bristol has a long history of trading commodities, originally wool cloth exports and imports of fish, wine, grain and dairy produce, later tobacco, tropical fruits and plantation goods; major imports now are motor vehicles, grain, timber, fresh produce and petroleum products. Deals were originally struck on a personal basis in the former trading area around The Exchange in Corn Street, and in particular, over bronze trading tables, known as “The Nails”. This is often given as the origin of the expression “cash on the nail”, meaning immediate payment, however it is likely that the expression was in use before the nails were erected. As well as Bristol’s nautical connections, the city’s economy is reliant on the aerospace industry, defence, the media, information technology and financial services sectors, and tourism. The former Ministry of Defence (MoD)’s Procurement Executive, later the Defence Procurement Agency, and now Defence Equipment & Support, moved to a purpose-built headquarters at Abbey Wood, Filton in 1995. The site employs some 7,000 to 8,000 staff and is responsible for procuring and supporting much of the MoD’s defence equipment.
