This once excellent capital city, masterminded 80 km from Ayutthaya was squashed by the Burmese outfitted power in 1767 and is at present an UNESCO world heritage site. A broad number of palaces, temples and chedis are yet standing. In 1782 Ayutthaya transformed into the capital of Thailand. The main sights fuse the huge bronze statues of Vihara Phra Mongkhon Bophit, moreover Wat Phra Sri Sanphet and Wat Yai Chai Mang Khon.

It's large bronze seated Buddha image or Phra Mongkhon Bophit is one of the largest bronze Buddha images in Thailand with its measures of 9.5 meters across the lap and a height of 12.5 meters. The Buddha image is seated in the position of Subduing Mara. During the second fall of Ayutthaya, the building and the image were badly destroyed by fire. The present Vihara and Buddha image have been reconstructed and renovated in the reign of King Rama V. The open area located east of the Vihara was formerly Sanam Luang, where royal cremation ceremonies took place.

And unlike many of the other ancient sites in Ayutthaya, this is still an active temple where monks reside. Thai people visit Wat Yai Chai Mongkhon to not only pay respects to Buddha, but also to pay homage to one of the most respected kings in Thai history, King Naresuan the Great.

Wat Phra Sri Sanphet is situated on the city island in Ayutthaya’s World Heritage park in Pratu Chai Sub-district. It has been registered as a national historic site by the Fine Arts Department since 5 March 1935. This monastery was the most important temple of Ayutthaya and situated within the Grand Palace grounds. It served as a model for the Temple of the Emerald Buddha in Bangkok.

Wat Lokaya Sutha, “the temple of the Earth” is located near the North West tip of the historical island near the old Royal Palace and Wat Phra Si Sanphet. Highlight of the monastery is its 42 meter long Reclining Buddha image, usually draped in orange cloth. Apart from the central prang which is in fairly good condition, little more than the base of the main buildings remains today.

Wat Mahathat (Temple of the Great Relics) is located almost right in the center of Ayutthaya. Apart from being the symbolic center where the Buddha's relics were enshrined, Wat Mahathat was also the residence of the Supreme Patriarch or leader of the Thai Buddhist monks. The temple is believed to be built during the 14th century A.D. (the early Ayutthaya period).
