The most important temple in the old royal palace grounds, and Ayutthaya's equivalent of Bangkok's Wat Phra Kaew. The three iconic bell-shaped chedis, built between 1448 and 1530, contained the ashes of three Ayutthayan kings and have become the symbol of the city.
The temple was never a residence for monks. It served exclusively as a royal chapel within the palace compound. What remains today gives the clearest sense of how grand Ayutthaya must have been at its peak.
