This Wat Na Phra Meru escaped destruction during the Burmese attack in 1767 because it was used as the invading army's headquarters. It was also the site where the Burmese king was fatally injured after firing a defective cannon. His death ended the sacking of Ayuthaya.

Restoration of the temple, which was originally built in 1546, took place during the reign of King Rama III of the Bangkok era. The primary draw here is the main bòt (central sanctuary) which contains an amazing carved wooden ceiling depicting the Buddhist heavens, with Mt Sumeru in the centre. There is also a splendid Ayuthaya-era Buddha image sitting 6m high. The unique characteristics of the Ayuthaya artistic style was to depict Buddha as a king; also note how detailed and human-like the facial features are, another departure from traditional Buddha images. Inside a smaller wíhǎan (large hall)behind the bòt is a green-stone Buddha from Sri Lanka; it's in a European pose (sitting in a chair), and is said to be 1300 years old. The walls of the wíhaan show traces of 18th- or 19th-century murals.
