Colchester in the context of "Clacton on Sea"

Londinium, also known as Roman London, was the capital of Roman Britain during most of the period of Roman rule. Most twenty-first century historians think that it was originally a settlement established shortly after the Claudian invasion of Britain, on the current site of the City of London, around 47–50 AD, but some defend an older view that the city originated in a defensive enclosure constructed during the Claudian invasion in 43 AD. Its earliest securely-dated structure is a timber drain of 47 AD. It sat at a key ford at the River Thames which turned the city into a road nexus and major port (which was built between 49 and 52 AD), serving as a major commercial centre in Roman Britain until its abandonment during the 5th century.

Following the foundation of the town in the mid-1st century, early Londinium occupied the relatively small area of 1.4 km (0.5 sq mi), roughly half the area of the modern City of London and equivalent to the size of present-day Hyde Park. In 60 or 61 AD, the rebellion of the Iceni under their queen, Boudica, compelled the Roman forces to abandon the settlement, which was then razed. Following the defeat of Boudica by the Roman governor Gaius Suetonius Paulinus a military installation was established, and the city was rebuilt. It had probably largely recovered within about a decade. During the later decades of the 1st century, Londinium expanded rapidly, becoming Britannia's largest city, and it was provided with large public buildings such as a forum and amphitheatre. By the 2nd century, Londinium had grown to perhaps 30,000 or 60,000 people, almost certainly replacing Camulodunum (Colchester) as the provincial capital, and by the mid-2nd century Londinium was at its height. Its forum basilica was one of the largest structures north of the Alps when Emperor Hadrian visited Londinium in 122. Excavations have discovered evidence of a major fire that destroyed much of the city shortly thereafter, but the city was again rebuilt. By the second half of the 2nd century, Londinium appears to have shrunk in both size and population.

Essex (/ˈɛsɪks/ ESS-iks) is a ceremonial county in the East of England. It is bordered by Cambridgeshire and Suffolk to the north, the North Sea to the east, Kent across the Thames Estuary to the south, Greater London to the south-west, and Hertfordshire to the west. The largest settlement is Southend-on-Sea.

The county has an area of 3,670 km (1,420 sq mi) and had an estimated population of 1,929,610 in 2024. The south of the county is densely populated, and includes Southend-on-Sea in the south-east and Basildon in the south-centre. The centre and north of the county is more rural, and its principal settlements include Chelmsford in the centre and Colchester in the north-east. The districts of Chelmsford, Colchester and Southend hold city status. For local government purposes Essex comprises a non-metropolitan county, with twelve districts, and two unitary authority areas: Thurrock and Southend-on-Sea. The county historically included north-east Greater London, the River Lea forming its western border.

The Trinovantes or Trinobantes were one of the Celtic tribes of Pre-Roman Britain. Their territory was on the north side of the Thames estuary in current Essex, Hertfordshire and Suffolk, and included lands now located in Greater London. They were bordered to the north by the Iceni, and to the west by the Catuvellauni. Their name possibly derives from the Celtic intensive prefix "tri-" and a second element which was either "nowio" – new, so meaning "very new" in the sense of "newcomers", but possibly with an applied sense of vigor or liveliness ultimately meaning "the very vigorous people". Their capital was Camulodunum (modern Colchester), one proposed site of the legendary Camelot.

The East of England is one of nine official regions of England at the first level of ITL for statistical purposes. It consists of the ceremonial counties of Bedfordshire, Cambridgeshire, Essex, Hertfordshire, Norfolk and Suffolk. The northern part of the region, consisting of Norfolk, Suffolk and Cambridgeshire, is known as East Anglia. The latter region has been considered an informal region in its own right due to its differing cultural identity.

The population of the East of England in 2024 was 6,576,306. Bedford, Luton, Basildon, Peterborough, Southend-on-Sea, Norwich, Ipswich, Colchester, Chelmsford and Cambridge are the most populous settlements. Peterborough is the largest city in the East of England at 215,000. The southern part of the region lies in the London commuter belt.

Camulodunum (/ˌkæm(j)ʊloʊˈdjuːnəm/ KAM-(y)uu-loh-DEW-nəm; Latin: CAMVLODVNVM), the Ancient Roman name for what is now Colchester in Essex, was an important castrum and city in Roman Britain, and the first capital of the province. A temporary "strapline" in the 1960s identifying it as the "oldest recorded town in Britain" has become popular with residents and is still used on heritage roadsigns on trunk road approaches. Originally the site of the Brythonic-Celtic oppidum of Camulodunon (meaning "stronghold of Camulos"), capital of the Trinovantes and later the Catuvellauni tribes, it was first mentioned by name on coinage minted by the chieftain Tasciovanus some time between 20 and 10 BC. The Roman town began life as a Roman legionary base constructed in the AD 40s on the site of the Brythonic-Celtic fortress following its conquest by the Emperor Claudius. After the early town was destroyed during the Iceni rebellion in AD 60/61, it was rebuilt, reaching its zenith in the 2nd and 3rd centuries. During this time it was known by its official name Colonia Claudia Victricensis (COLONIA CLAVDIA VICTRICENSIS), often shortened to Colonia Victricensis, and as Camulodunum, a Latinised version of its original Brythonic name. The town was home to a large classical temple, two theatres (including Britain's largest), several Romano-British temples, Britain's only known chariot circus, Britain's first town walls, several large cemeteries and over 50 known mosaics and tessellated pavements. It may have reached a population of 30,000 at its height.

Chelmsford (/ˈtʃɛlmzfərd/) is a city in Essex, England. It is the county town of Essex and one of three cities in the county, along with Colchester and Southend-on-Sea. It is located 31 miles (50 km) north-east of Charing Cross in London, and 22 miles (35 km) south-west of Colchester. At the 2021 census the built up area had a population of 110,625. It gives its name to the wider Chelmsford local government district which also covers an extensive surrounding area.

Chelmsford as a settlement started growing after 1100 AD, when a bridge across the River Can was built. The town grew in importance after King John issued a Royal Charter in 1196, allowing Chelmsford to host a market, and by 1219 the town had become the county town of Essex. Chelmsford was involved in the Peasants' Revolt of 1381, and King Richard II moved on the town after quelling the revolt in London. In 1516, King Henry VIII purchased the Boleyn estate, building Beaulieu Palace, located on the current site of New Hall School.

Coggeshall (/ˈkɒksəl/ or /ˈkɒɡɪʃəl/) is a village and civil parish in the Braintree district of Essex, England. It lies between Braintree and Colchester on the Roman road of Stane Street and the River Blackwater. At the 2021 census the parish had a population of 4,660 and the built up area had a population of 3,810.

It has almost 300 listed buildings and a market whose charter was granted in 1256 by King Henry III.
