    About Seoul

    Korea’s heart that never stops beating

    Seoul is the capital of South Korea and the political, economic, social, and cultural center of the country. This is a city where the past and the future come together. During the day, take a leisurely stroll along the alleyways of Gahoe-dong where the beautiful Hanok, Korean traditional houses, are located and, at night, take in the splendid night views of the city by visiting N Seoul Tower. Travelers can enjoy a moment of relaxation by Cheonggyecheon Stream, which flows peacefully through the heart of the city. Traditional markets are overflowing with the energy of “Seoulites,” the term used by the Seoul Metropolitan Government to refer to its citizens.
