From Roman Londinium to the Modern Financial Capital
London has many faces, but the true heart of the city lies within the ancient Square Mile. This walking tour explores the hidden layers of the City of London, where nearly two thousand years of history survive between modern towers, quiet alleys, medieval guilds, and the world’s most powerful financial institutions.
Starting near St Paul’s Cathedral and finishing in the insurance district around Lloyd’s of London, this route reveals the story of how a Roman trading settlement became the financial centre of the modern world. Along the way we encounter Roman remains, medieval churches, livery companies, coffee houses, markets, and the institutions that shaped global commerce.
This tour is designed for visitors who want to go beyond the usual sights and understand how London really works, past and present.

Full Description
We begin near St Paul’s Cathedral, one of the great symbols of London, standing on a site used for worship for over fourteen centuries. From here we explore the origins of the City itself, founded by the Romans in AD 47 as Londinium, a trading settlement on the River Thames that grew into the centre of Roman Britain.
Walking through Cheapside, once the main medieval market street, we discover how trade shaped the character of the City. Hidden churches rebuilt after the Great Fire of 1666 stand beside modern architecture, showing how London has repeatedly rebuilt itself after disaster.
In a small garden maintained by one of the ancient livery companies, we learn about the guilds that controlled trade in the medieval city, including the Goldsmiths, whose role in testing the nation’s coinage connected the Tower of London, Westminster, and the City in a unique royal system of authority.
At Guildhall, the historic centre of City government, we explore the unusual independence of the City of London, its Lord Mayor, its ancient courts, and its role in shaping the political and commercial life of the country for centuries.
Nearby, the Guildhall Art Gallery reveals the remains of a Roman Amphitheatre buried beneath the modern street, a reminder that the City has been continuously occupied since antiquity.
Moving eastwards, we walk through streets once associated with the Jewish community, Georgian merchants, and great political figures such as Benjamin Disraeli, before reaching Cheapside again, where royal processions once entered the City through the ceremonial boundary at Temple Bar.
Around Poultry and the Bank junction we see the centre of the modern financial world. Here stand the Royal Exchange, founded in the sixteenth century to rival the markets of Europe, and the Bank of England, one of the most influential financial institutions in history.
From here we enter the narrow alleys of Lombard Street, where Italian bankers, merchants, and goldsmiths developed the early banking system that later made London the financial capital of the world. Symbols above the doors still mark the houses of former banks, a tradition from the time before street numbers existed.
In Change Alley and nearby streets we follow the story of the coffee houses of the seventeenth century. These small meeting places became the birthplace of modern finance, insurance, and the stock market, where merchants, ship owners, and traders gathered to exchange news, make deals, and insure their cargo.
We continue through George Yard and nearby lanes connected with Charles Dickens, the abolition movement, and the early campaigns against the slave trade, before reaching Cornhill, one of the oldest parts of the City.
At Leadenhall Market we step into a Victorian iron and glass arcade built on the site of the Roman basilica, once the administrative centre of Londinium. This market shows the continuity of trade in the City from the Roman period to the present day.
The walk finishes in the modern insurance district at Lloyd’s of London, where the story of the City comes full circle. What began as a Roman trading post has become one of the most important financial centres in the world, where risks are insured, fortunes are made, and global business is conducted every day.
This tour reveals the hidden structure of London, layer by layer, from ancient walls to modern skyscrapers.
