The City of London is a financial district in the heart of the capital. It’s no surprise, with its central location, that the City of London is home to the Stock Exchange and Bank of England. But, there is much history to be found here, too, through mediaeval alleyways that have tales of adventure. Pudding Lane is in the City of London, a small street that became infamous in 1666 when Thomas Farriner's bakery caught fire and began The Great Fire of London, a disaster that would leave 85% of London homeless. You’ll also be able to take in the beauty of the 17th century St. Paul’s Cathedral, learn about the city’s history at the Museum of London, and then catch a performance at the Barbican Arts Centre. The City of London is sometimes referred to as the Square Mile, and it spans 1.12 square miles.
