Colchester

Colchester (/ˈkɒltʃɛstər, ˈkoʊl-, -tʃɪst-/ ^ⓘ KO(H)L-chest-ər, -⁠chist-) is a city in north-eastern Essex, England. At the 2021 census the built up area had a population of 130,245, making it the second-largest settlement in Essex, after Southend-on-Sea. It gives its name to the wider Colchester local government district which also covers an extensive surrounding area. The demonym is Colcestrian.

Colchester occupies the site of Camulodunum, the first major city in Roman Britain and its first capital. Colchester therefore claims to be Britain's first city. It has been an important military base since the Roman era, with Colchester Garrison currently housing the 16th Air Assault Brigade.

The city is on the River Colne, and lies 50 miles (80 kilometres) north-east of London. It is connected to London by the A12 road and the Great Eastern Main Line railway. Colchester is less than 30 miles (50 km) from London Stansted Airport and 20 miles (30 km) from the port of Harwich.

Attractions in and around the city include St Botolph's Priory, Colchester Zoo, and several art galleries. Colchester Castle was constructed in the eleventh century on earlier Roman foundations; it now contains a museum. The main campus of the University of Essex is located between Colchester and Wivenhoe. Local government is the responsibility of Colchester City Council and Essex County Council.
