Here can you see the flags of the biggest cities in the world. Can you guess them all? If the city doesnät have a flag nor a coat of arms then the city's flag is replaced by the country's flag.
Population by metropolitan area, not city proper
If the city doesn't have a flag or it doesn't open in Commons, then the coat of arms is shown instead
Indian cities except Delhi can't be included because the cities don't have flags and India's flag doesn't open in Commons.
