Wat Nak, or the Monastery of the Naga, is situated in the western area of Ayutthaya, off the city island in the Pak Kran Sub-district, west of Khlong Takhian (1).
The temple lies near the present (new) active Wat Klang Khlong Takhian and its ancient position, Wat Klang.
The remains of the monastery reside in an area covered with vegetation.
The site is a large brick mound, and there is still a standing damaged chedi. Traces of broken Buddha images can be seen.
The monastery is mentioned on a 19th-century map but is not indicated on Phraya Boran Ratchathanin’s map of 1926 CE. All Fine Arts Department maps since 1974 CE show the site.
Its historical background and period of construction are not known.
Near Wat Nak was one of the former six southern ferries (2) across the old Lopburi River - at present the Chao Phraya River (1) - linking the monastery with Tha Wang Chai (Palace of Victory Landing) near Wat Wang Chai. [1]
