Wat Yai Chai Mongkhon or the Great Monastery of Auspicious Victory is located
off the City Island in the southeastern area at present Phai Ling Sub-district. To its east
side, just over the moat, there were two small temples situated. They are called Ancient
Temple No 1 and 2.

Temple No 1 was located south of Temple No 2. From this temple only a restored
bell-shaped chedi remains. The vihara was lost in time.  The architectural style of the
stupa is from the Middle Ayutthaya period but restored in the Late Ayutthaya era. It is
obvious that this chedi had been redone completely by the Fine Arts Department. The
chedi is classic with a square platform, a round base, a bell-shaped dome, square
harmika and spire.

The historical data about the monastery and its construction are unknown.

The site is located in geographical coordinates: 14° 20' 42.87" N, 100° 35' 40.11" E.
