City of London Hidden Alleys Free Tour
Roman walls and medieval lanes between the skyscrapers
The "Square Mile" hides its 2,000 years well: Roman walls in parking garages, churches Wren rebuilt after the Great Fire wedged between glass towers, and alleys where Dickens drank that still serve at the same bar. This tour finds the ancient city the commuters walk past every day.
The walk starts at Trafalgar Square (Trafalgar Square, London WC2N) and runs daily at 11:00. It lasts around 2.5 hours, is offered in English, Spanish, and the group is capped at 25 people so the experience stays personal. Look for the guide with the green FreeTour sign.
