A capital city is the primary city in a country or region where the government is located. It often houses important buildings like the parliament, presidential palace, and various government offices. Capital cities are usually central to political activities and decision-making, making them significant for the nation's governance.
In addition to politics, capital cities often serve as cultural and economic hubs. They may feature famous landmarks, museums, and theaters, attracting tourists and residents alike. For example, Washington, D.C. in the United States is known for its iconic White House and Capitol Building, while London in the UK boasts the historic Buckingham Palace.
