Excavations at the site of Wat Bua resulted in the discovery of a miniature reproduction of a vihara in baked clay dating from the 15th - the 18th century CE. The model is displayed in the Chao Sam Phraya Museum.
There are no traces anymore visible of the monastery above ground level.
Locals in the vicinity recalled a chedi in situ in earlier times, but except for some scattered bricks, not much was seen above ground level as the site is covered in vegetation.
Historical data about the monastery and its construction are unknown.
Wat Bua shows on 1974, 1993 and 2007 CE Fine Arts Department maps.
Some temple remains were excavated by the Fine Arts Department (FAD) in geographical coordinates: 14° 22' 39.92" N, 100° 33' 25.04" E.
Footnotes:
(1) Khlong Sra Bua, or the Lilly Pond Canal, is a canal situated in the northern area, off the city island, in the Khlong Sra Bua District. The waterway splits from Khlong Hua Ro between Wat Ngiu (defunct) and Wat Si Liam. The canal has its mouth at the City Canal (Khlong Mueang) between Wat Na Phra Men and Wat Mai in front of the northeastern corner of the Grand Palace. The canal was a shortcut in the old Lopburi River.
(2) Thung Khwan, or "Field of Fumes", is an area north of the city of Ayutthaya bordered on the north by Thung Lum Phli, on the east by Khlong Sra Bua and Thung Kaeo, in the south by the old Lopburi River and in the west by Thung Phukhao Thong. This area was likely related to crematory services.
