Bangkok (Thai: กรุงเทพฯ) is the capital) of Thailand and, with a population of over eleven million inhabitants, by far its largest city. Its high-rise buildings, heavy traffic congestion, intense heat and naughty nightlife do not immediately give you a warm welcome — but don't let your first impression mislead you. It is one of Asia's() most cosmopolitan cities with magnificent temples and palaces, authentic canals, busy markets and a vibrant nightlife that has something for everyone.

For years, it was only a small trading post at the banks of the Chao Phraya River, until King Rama I, the first monarch of the present Chakri dynasty, turned it into the capital of Siam in 1782, after the burning of Ayutthaya by Burmese invaders. Since then, Bangkok has turned into a national treasure house and functions as Thailand's spiritual, cultural, political, commercial, educational and diplomatic centre.

Bangkok is a huge and modern city humming with nightlife and fervor. Administratively, it is split up into 50 districts (เขต khet), which are further split into 154 subdistricts (แขวง khwaeng), but these are more often used in official business and for addresses. Visitors will find the conceptual division below of the main areas more useful for getting around.
