During the 19th century, London grew enormously to become a global city of immense importance. It was the largest city in the world from about 1825,[1] the world's largest port, and the heart of international finance and trade.[2] Railways connecting London to the rest of Britain, as well as the London Underground, were built, as were roads, a modern sewer system and many famous sites.
