Bristol is a city, unitary authority area and ceremonial county in South West England, 105 miles (169 km) west of London, and 24 miles (39 km) east of Cardiff.

With an estimated population of 421,300 for the unitary authority in 2008, 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. It received a Royal Charter in 1155 and was granted County status in 1373. From the 13th century, for half a millennium, it ranked amongst the top three English cities after London, alongside York and Norwich, on the basis of tax receipts, until the rapid rise of Liverpool, Birmingham and Manchester during the Industrial Revolution in the latter part of the 18th century. It borders the counties of Somerset and Gloucestershire, and is also located near the historic cities of Bath to the south east and Gloucester to the north. The city is built around the River Avon, and it also has a short coastline on the Severn Estuary, which flows into the Bristol Channel.
