The City of London stands where the Romans built Londinium around AD 43, inside a wall whose pieces can still be seen. After the Great Fire of 1666, Christopher Wren designed the new St Paul's Cathedral, and the City grew into a business district.

Londinium
Around AD 43 Roman legions set up a settlement called Londinium where the City of London is now. Its bridge over the River Thames made it a meeting point of roads and a major port, and a major centre of trade in Roman Britain.
From the records: “The Roman legions established a settlement known as "Londinium" on the current site of the City of London around AD 43.”
Late 1st century
🏟️
Britannia's largest city
In the later 1st century Londinium grew fast and became the largest city in Britannia, with big public buildings such as a forum and an amphitheatre. The amphitheatre stood where the Guildhall is now, and was rediscovered in 1988.
From the records: “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.”

Londinium at its height
In the early 2nd century Londinium was at its height, with between 45,000 and 60,000 people around 140. By the late 2nd century it had many large stone buildings, some with wall paintings, floor mosaics and hypocausts (heating under the floor).
From the records: “During the early 2nd century, Londinium was at its height, having recovered from the fire and again had between 45,000 and 60,000 inhabitants around 140, with many more stone houses and public buildings erected.”

The London Wall
In the late 2nd or early 3rd century a fort on the north-west edge of the city became part of a wall right round the city. Nobody knows why such a large and expensive wall was built. In 2023 a section of it went on show to the public at the City Wall at Vine Street museum.
From the records: “The precise date of this change is unknown, and no surviving source explicitly states that Londinium was "the capital of Britain," but there are several strong indications of this status: 2nd-century roofing tiles have been found marked by the "Procurator" or "Publican of the Province of Britain at Londinium", the remains of a governor's palace and tombstones belonging to the governor's staff have been discovered, and the city was well defended and armed, with a new military camp erected at the beginning of the 2nd century in a fort on the north-western edge of the city, despite being far from any frontier.”

A wall by the river
After Saxon pirates raided Londinium several times in the late 3rd century, building of a wall along the river began in 280. It was repaired around 390. Digging at the Tower of London in 1977 showed that part of the Tower's inner wall was once part of this Roman riverside wall.
From the records: “After Londinium was raided on several occasions by Saxon pirates in the late 3rd century, construction of an additional riverside wall, built in phases, began in 280 and was repaired c. 390.”
