London is the capital city and largest city of the United Kingdom, home to around 9 million inhabitants. It is the center of political and social activities in the country and a top tourist destination, known for its museums, galleries, and theaters that attract visitors year-round. The sprawling metropolis is divided into Old London and 32 districts and boasts a rich history, though it has endured several disasters over time, with many historic monuments still standing today, such as the prestigious Parliament building originally constructed as Westminster Palace.
