About Phra Nakhon Si Ayutthaya Province
Phra Nakhon Si Ayutthaya, usually shortened to Ayutthaya, surrounds the former Siamese capital that ruled much of mainland Southeast Asia from 1351 until its sack by Burmese forces in 1767. The old city sits on an island formed by the Chao Phraya, Pa Sak, and Lopburi rivers, and its temple ruins, royal palaces, and crumbling brick prangs make up the UNESCO-listed Ayutthaya Historical Park. The famous Buddha head wrapped in the roots of a bodhi tree at Wat Mahathat is one of Thailand's most recognisable images.
