About City of London
The City of London is the historic, financial, and symbolic heart of the capital. Often called the Square Mile, it occupies the ancient core of London, where Roman Londinium once stood. Today, the area combines some of the city’s oldest streets with some of its most modern architecture, creating a powerful contrast between heritage and global business. Visitors will find major landmarks such as St Paul’s Cathedral, The Monument, Guildhall, the Bank of England, Mansion House, Leadenhall Market, Tower Hill, and sections of the old Roman and medieval city walls. At the same time, the skyline is shaped by modern office towers, including some of London’s most recognisable commercial buildings. The City is busy during the working week, when professionals, bankers, lawyers, tourists, and commuters fill its streets. On weekends, it often becomes quieter, allowing visitors to appreciate its hidden churches, narrow lanes, courtyards, gardens, and historic pubs. For a local guide or tourism page, the City of London is best presented as a place of contrasts: ancient and modern, formal and atmospheric, commercial and cultural. It is ideal for history walks, architectural tours, business travel, sightseeing, and discovering the origins of London itself.
