Excavation work was done in 2017 CE by the 3rd Regional Office of Fine Arts, followed by a conservation and development phase from 2020 to 2021.
Visitors can climb the Mon-Burmese-styled base until the foot of the chedi, from which the surrounding rice fields and the town of Ayutthaya can be seen.
The architecture of the monastery
Wat Phukhao Thong was abandoned in the last Siamese-Burmese war, which heralded the end and fall of the mighty city of Ayutthaya. Monks settled again in 1957 CE near the ruins of the temple.
The sloping base of Chedi Phukhao Thong is unique in Ayutthaya. On the base rest a Thai-style chedi, very similar to the Chedi Sri Suriyothai. A typical feature of a Thai chedi is the row of columns over the square harmika directly under the umbrella.
There was a structure built on the remains of the ancient ruin. The foundations and part of the pillars of the old ubosot or ordination hall are still visible. The hall is rectangular, 40 m long and 11 m wide. The building had front and back porches and two gates, east and west. Its entrance is northeast. The structure was torn down in 2017 CE due to excavation and renovation, and a new hall was built.
Next to the ordination hall is a vihara measuring approximative 12 m long and 6 m wide. The single entrance faces northeast.
On the southwest side are four bell-shaped chedis with 12 rabbeted angles at par with the principal Chedi Phukhao Thong. The chedis also have four niches, one on each side.
An outer wall and moat surround the whole complex.
Kaempfer refers to the monastery as follows: “Next to this pyramid are some temples and colleges of the Talapoins, which are taken in with particular neat brick walls. The temples are of a very curious structure, covered with several roofs, supported by columns.” [17]
The temple, in earlier times, could not be reached on foot as there were no roads leading to it, and the area around was very swampy. A canal connected the monastery to the main river.
