Phra Nakhon Si Ayutthaya

The province spans 2,557 square kilometers of flat river plains, formed by the convergence of the Chao Phraya, Pa Sak, and Lopburi Rivers.

From 1350 to 1767, the province served as the capital of Siam under 33 kings from five dynasties until Burmese forces destroyed the city.

The province contains numerous temples and structures that demonstrate the architectural fusion of Khmer and Sukhothai styles in their prangs and stupas.

The province maintains direct transportation connections to Bangkok through regular train services, buses, and boat routes along the Chao Phraya River.

The Honda manufacturing facility in the province produces 300,000 hybrid electric vehicles annually, combining industrial progress with historical preservation.
