Once the Largest City on Earth

Ayutthaya may have held around one million people by 1700, which would have made it the largest city in the world at the time. Burmese forces destroyed it in 1767, and the capital moved downriver to what became Bangkok.

The clock: Ayutthaya keeps UTC+7. A Buddha head grown into the roots of a banyan tree at Wat Mahathat is its best-known image.
