WAT MAI BANG KAJA (วัดใหม่บางกะจะ)
Wat Mai or the New Monastery is located off the city island in the southern area of
Ayutthaya in Samphao Lom Sub-district. The monastery is strategically situated on the
confluence of the
Chao Phraya River and the (new) Pa Sak River, just opposite the
Phet Fortress and the old harbour. Wat Nang Kui is situated on its northwestern side. On
its east on the opposite side of the river stands
Wat Phanan Choeng.

The original name was Wat Bang Kaja, but the temple decayed and was rebuilt, hence
the name the
New Monastery or Wat Mai.

Wat Mai is used by the Buddhist clergy. In situ is a classic temple consisting of an
ordination hall (ubosot), a large chedi and a vihara. The large chedi belongs to the vihara.
The ubosot, built in Early Ayutthaya style (1351 - 1488 AD), stands in a strange
north-south axis position, rather unusual as monastic buildings are almost build on an
east-west axis, while the main Buddha image is looking into the direction of the rising sun.

Kaca village is mentioned in the Royal Chronicles of Ayutthaya. In 1549, after
King
Chakkraphat
(r. 1548-1569) came on the throne of Ayutthaya in an unstable period,
Burma seeing its chance to conquer the Siamese city state, invested Ayutthaya. Patani,
being a vassal state, sent down a naval force in assistance of Ayutthaya. The chronicles
mention that the Patani fleet anchored in front of the Bang Kaja Monastery. [1]

At that moment the Phraya Sultan of Tani brought his naval force of two hundred
yayap boats in to assist the government in the war. On arrival they anchored
[BDEF: in front of] [C: at] the Kutbangkaca Monastery.

The Chronicles found at the British Museum state that in year 924 of the Chula Sakarat
(1)
King Maha Thammaracha (r. 1569 - 1590) ] had the moat by the front ramparts
on the east dug ten wa (2) wide and three wa deep from the
Maha Chai Fort at the Back
Palace (3) down  to connect with Kaca village. [1]

In 924, a year of the dog, fourth of the decade, the King had the Royal Metropolis
renovated. He had the moat by the front ramparts on the east dug ten wa wide and
three wa deep from the Maha Chai Fort at the Back Palace down to connect with
Kaca Village [Canal?]. Then he had the city walls moved out to the banks of the
river, the outer limit of the Royal Metropolis, and connected with the Maha Chai
Fort, and from the Maha Chai Fort connected down to the Phet Fort.

The important Nam Won Bang Kaja floating market (4), situated near the anchorage
for foreign boats and junks, was held in the vicinity of this temple, at the whirlpool (5) of
Bang Kaja in front of Wat Chao Phanan Choeng. It was a densely populated area close
to many floating markets and gathering grounds. [2]

Wat Bang Kaja is indicated on François Valentyn's map (1724-6)
Groote Siamse
Rievier Me-Nam Of Te Moeder Der Wateren In haren loop met de vallende
Spruyten Verbeeld
as Wat May. (6)

The site is indicated on a
mid-19th century map as Wat Mai Bang Kraja and on Phraya
Boran Rachathanin's map drafted in 1926 as Wat Mai.

Wat Mai Bang Kaja is located in Geo Coord: 14° 20' 41.13" N, 100° 34' 28.76" E.
