Ayutthaya Historical Park

Ayutthaya Historical Park covers the ruins of the old city of Ayutthaya, Phra Nakhon Si Ayutthaya province, Thailand. The city of Ayutthaya was founded by King Ramathibodi I in 1351,^[a] though it is likely to be significantly older, based on evidence showing that the area was already populated during the Mon Dvaravati period. Sources further mention that around 850 AD, the Khmers occupied the area and established a stronghold there, naming it Ayodhya, after one of the holiest Hindu cities in India of the same name. The early history of Ayutthaya is connected to this Khmer settlement. Additionally, Prince Damrong has also attested to the existence of a city named Ayodhya, founded by the Khmers ruling from Lopburi at the point where the three rivers meet. An excavation map shows traces of an ancient baray close to the southwestern tip of Wat Yai Chai Mongkhon, which could have been built on a former important Khmer temple complex.
