Le Palais Royal (Thai : พระบรมมหาราชวัง, Phra Borom Maha Ratcha Wang) de Bangkok a été construit en 1782 par le roi Rama Ier sur la rive gauche (orientale) de la Chao Phraya. Il abrite non seulement la résidence royale et la salle du trône, mais aussi un grand nombre de bureaux gouvernementaux et le temple du Bouddha d'Émeraude (Wat Phra Kaeo, récemment rénové).
Il couvre une surface de 21,8 hectares et est entouré de quatre murs de 1 900 m de long.
Bangkok is the capital and the most populous city of Thailand. It is known in Thai as Krung Thep Maha Nakhon (กรุงเทพมหานคร, pronounced [krūŋ tʰêːp máhǎː nákʰɔ̄ːn] ( listen)) or simply Krung Thep (help·info). The city occupies 1,568.7 square kilometres (605.7 sq mi) in the Chao Phraya River delta in Central Thailand, and has a population of over eight million, or 12.6 percent of the country's population. Over fourteen million people (22.2 percent) live within the surrounding Bangkok Metropolitan Region, making Bangkok an extreme primate city, dwarfing Thailand's other urban centres in terms of importance.
Bangkok traces its roots to a small trading post during the Ayutthaya Kingdom in the 15th century, which eventually grew in size and became the site of two capital cities: Thonburi in 1768 and Rattanakosin in 1782. Bangkok was at the heart of Siam's (as Thailand used to be known) modernization during the later nineteenth century, as the country faced pressures from the West. The city was the centre stage of Thailand's political struggles throughout the twentieth century, as the country abolished absolute monarchy and underwent numerous coups and uprisings. The city grew rapidly during the 1960s through the 1980s and now exerts a significant impact among Thailand's politics, economy, education, media and modern society.
