Wat Mongkut, or the Monastery of the Crown, was situated off the city island in the northern area of Ayutthaya, in the Khlong Sra Bua Sub-district. The temple was located in Thung Kaeo (1).

Wat Mongkut stood west of Wat Phrao, south of Wat Tamnak and 400 metres north of Wat Mae Nang Plum.

In the vicinity of Wat Phrao, and thus not far from Wat Mongkut, was a village where Brahman (likely Indians) and Thai make fragrant powder and oil, krajae scented water (2), krajae incense sticks, kradat incense sticks (3), and perfumes for sale. [1]

The date of establishment and the history of Wat Mongkut are unknown.

In situ is a medium-sized twenty-rabbeted-angled chedi common in the late Ayutthaya period (1733-1767 CE). There are niches in the relic chamber. In some sections, the decorative stucco is still well-preserved. No remains of an ordination hall, a vihara or outer walls were seen. The ruin is presently obscured by trees and other vegetative growth and tucked away between several houses.

Wat Mongkut does not show on Praya Boran Rachathanin’s 1926 CE map. The monastery was mentioned for the first time on a 1993 CE Fine Arts Department map.

The temple ruins are in geographical coordinates: 14° 22' 17.67" N, 100° 34' 3.54" E.
