Bangkok

Bangkok is the capital and largest city of Thailand, located in the central part of the country on the Chao Phraya River, not far from the Gulf of Thailand. The city developed on a low and relatively flat plain shaped by the river and its surrounding waterways. Its location has influenced both its history and its urban development, while canals, known locally as khlongs, have long formed part of the city's landscape.

Bangkok was established as the capital of the Kingdom of Siam in 1782 under King Rama I, after the capital was moved from Thonburi to the eastern bank of the Chao Phraya. The historic area includes important sites such as the Grand Palace, Wat Phra Kaew and Wat Arun. Bangkok later expanded far beyond its historic core and became a major centre for government, commerce, education, culture and tourism. Its extensive metropolitan area now includes numerous residential and industrial districts.

Bangkok has a tropical monsoon climate, with high temperatures and substantial humidity for much of the year. The city experiences a distinct rainy season, influenced by the Asian monsoon, while the period from roughly November to February is generally cooler and drier. Because Bangkok is built on low-lying ground, flooding can occur during periods of heavy rainfall, especially when high tides and water levels in the Chao Phraya coincide with intense rain.

The city has developed drainage systems, canals, pumps and other infrastructure to manage water. Bangkok is also an important transport hub, served by highways, railways, buses, river boats and urban rail systems such as the BTS Skytrain and MRT. Suvarnabhumi and Don Mueang airports connect the capital with destinations in Thailand and abroad. Today, Bangkok combines historic temples and palaces with modern commercial districts, universities and densely populated neighbourhoods, reflecting the rapid urban growth of Thailand.
