A City of History

One of the defining facts about London is its extraordinary history. Founded by the Romans in AD 47 as Londinium, it has stood for nearly 2,000 years. Over the centuries it has been a site of coronations, revolutions, plagues, fires, and wars. Some highlights include:

The Great Fire of London (1666): A catastrophic blaze that destroyed much of the medieval city but paved the way for new architecture and wider streets.
The Blitz (1940–41): German bombing raids during World War II caused immense destruction, yet London’s resilience became a symbol of British spirit.
Royal Traditions: Westminster Abbey has been the coronation site for English and British monarchs since 1066.
The Tower of London: Once a royal palace, then a prison, and now the home of the Crown Jewels, it reflects nearly 1,000 years of English history.

Walking around London often feels like stepping through time, as Roman walls, medieval churches, Georgian squares, Victorian markets, and futuristic skyscrapers stand side by side.

A City of Diversity

London is one of the most multicultural cities in the world. Over 300 languages are spoken, and people from more than 200 different nationalities live here. This diversity makes London unique in terms of food, festivals, fashion, and everyday life.
