The early port
In the first century AD, the invading Romans established a settlement called Londinium on the River Thames.
They started building at the point furthest downriver where they could construct a bridge.
Londinium became an important Roman trading centre and by the Middle Ages, London had become the capital of England.
By this time almost two-thirds of the country's trade went through the port.
Opportunities and services
London was the royal, administrative, judicial, commercial and cultural centre of Britain. It offered merchants opportunities and services that other British ports could not.
