A capital city, or capital town or capital, is a city or town, specified by law or constitution, by the government of a country, or part of a country, such as a state, province, or county. It usually serves as the location of the government's central meeting place and offices.
Most of the country's leaders, embassy and officials work in the capital city. This does not have to be the case though: Monaco, Nauru, Switzerland and Vatican City are examples of countries that do not have a capital city.
