Bangkok (Thai: กรุงเทพฯ Krung Thep)  is the capital ofThailand and by far its largest city with an estimated population of over 11 million.
Bangkok is one of Asia's most cosmopolitan cities. Created as the Thai capital in 1782 by the first monarch of the present Chakri dynasty, Bangkok is a national treasure house and Thailand’s spiritual, cultural, political, commercial, educational and diplomatic centre.
Bangkok is a huge and modern city humming with nightlife and fervour. Administratively, it is split up into 50 khet (districts), which are further split into 154 khwaeng (แขวง), 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.

Siam Square The area around Siam Square, including Ratchaprasong Intersection and Ploen Chit is Bangkok's modern commercial core, full of glitzy malls and hotels. The Skytrain intersection at Siam Square is the closest thing Bangkok has to a centre.
Sukhumvit The long Sukhumvit Road is Bangkok's nightlife district filled with quality hotels, restaurants and clubs. Part of its nightlife represents Bangkok's naughty image, particularly Soi Cowboy and Nana Plaza.
Silom To the south of Sukhumvit, the area around Silom Road and Sathorn Road is Thailand's sober financial center by day, but Bangkok's primary party district by night when quarters like the infamous Patpong come alive.
Rattanakosin Between the river and Sukhumvit lies the densely packed "Old Bangkok", home to Bangkok's best-known sights, such as the Grand Palace and Wat Pho.
Khao San Road On the northern part of Rattanakosin, Bangkok's backpacker mecca Khao San Road and the surrounding district of Banglamphu have everything the budget traveler is looking for.
Yaowarat and Pahurat Along Yaowarat Road you will find Bangkok's Chinatown, while Pahurat Road is the home of the sizable Indian community. This multicultural district is filled with a Sikh Temple (Sri Guru Singh Sabha) and markets selling food, gold, fabrics, and Bollywood movies.
Dusit This leafy, European-style area is the political center of Thailand, home to numerous political institutions and the monarchy. Its breezy palaces, lush gardens and broad avenues give the district its distinct character.
Thonburi The quieter west bank of the Chao Phraya River, with Wat Arun and many small canals to explore.
Phahonyothin The area around Phahonyothin Road and Viphavadi Rangsit Road is best known for Pratunam, Chatuchak Weekend Market and Baiyoke Tower II. The sois around Ari offer some excellent nightlife.
Ratchadaphisek The district north of Sukhumvit centered around Ratchadaphisek Road (part of which is called Asoke). The sois of "Ratchada" are popular nightlife spots with the locals, as is the area around Royal City Avenue (RCA).
Ramkamhaeng Along Ramkamhaeng Road lies a vast residential area with big shopping malls and amusement parks (like Safari World). Each neighborhood has its own character, the most important ones being Bang Kapi and Min Buri.
