Geography

The Bangkok special administrative area covers 1,568.7 km2 (606 sq mi), making it the 68th largest province in Thailand. Much of the area is considered the city of Bangkok, therefore making it one of the largest cities in the world.[3] The Chao Phraya River, which stretches 372 km (231 mi), is Bangkok's main geographical feature. The Chao Phraya River basin, the area surrounding Bangkok, and the nearby provinces comprise a series of plains and river deltas that lead into the Bay of Bangkok about 30 km (19 mi) south of the city center. This gave rise to Bangkok's appellation as the "Venice of the East" due to the number of canals and passages that divide the area into separate patches of land. The city once used these canals, which were plentiful within Bangkok itself, as divisions for city districts. However, as the city grew in the second half of the 20th century, the plan was abandoned and a different system of division was adopted.
