Ayutthaya was, for 417 years, the capital of the Siamese. A magnificent city in the 17th and 18th centuries with a cosmopolitan character, it became one of Asia's most important trading hubs. The city fell on April 1767 at nightfall to the Burmese, never to arise of its ashes. 

In Ayutthaya's heyday, this was the largest temple in the city. The three main chedis restored include the ashes of three Ayutthaya kings. The temple served to conduct ceremonies within the royal court, such as the ritual of drinking an oath of allegiance and is regarded as a correspondence of Wat Mahathat in Sukhothai and a model for Wat Phra Sri Ratana Sasadaram (the royal temple of the Emerald Buddha) or Wat Phra Kaew in Bangkok. 

Wat Yai Chai Mang Khon remains one of the city's most famous and scenic holy sites. Uthong built this magnificent example of Buddhist religious architecture, the first ruler of the kingdom of Ayutthaya. 

In history, Wat Lokayasutharam temple was one of King Barommakote's travelling routes. The reclining Buddha is a giant white Buddha with a length of 42 meters and a height of 8 meters. Even though it is ancient, it is still in perfect condition, with a glowing face beaming with happiness and a lotus base platform supporting the head. 

Wat Mahathat was one of Ayutthaya’s most important temples. It enshrined Buddha relics and was the seat of the Supreme Patriarch of Buddhism and, thus, the centre of Buddhism in the Ayutthaya Kingdom. Wat Mahathat was a Royal monastery located close to the palace. The King performed important ceremonies here, such as the Royal Kathin ceremony. One of the temple’s most photographed objects is the head of a stone Buddha image entwined in the roots of a tree.
