Bangkok: The Dynamic Capital of Thailand

Bangkok, known locally as Krung Thep Maha Nakhon, serves as the vibrant capital and the primary economic, cultural, and political hub of Thailand. Often nicknamed the "City of Angels" or "The Big Mango," this sprawling metropolis is a unique blend of ancient traditions and cutting-edge modernity, situated in the heart of Central Thailand.

From its origins as a settlement in the 15th century to its official founding as the capital on April 21, 1782, by King Rama I, Bangkok has evolved into one of the most visited cities in the world. Today, it is managed as a special local administrative area by the Bangkok Metropolitan Administration.
