KHLONG PRATU JIN (คลองประตูจีน)
Text & maps by Tricky Vandenberg - May 2012
Khlong Pratu Jin or the Canal of the Chinese Gate is part of a waterway running
through the middle of Ayutthaya from north to south. The canal ran from the
Bridge to the Chinese water gate (Pratu Jin) one of the eleven water gates a that time;
and was an extension of
Khlong Pratu Khao Pluak. The canal was in fact a shortcut
(khlong lat) through the oxbow of the
Lopburi River and connected the old Lopburi
River, present
Khlong Mueang in the north with - what is today - the Chao Phraya River
in the south.

The north-south canal was filled in last century and is at present inexistent, with the
exception of a small stretch of water between
Wat Tha Sai and Wat Racha Praditsathan
near Pratu Khao Pluak. The canal, starting from Saphan Chikun, was crossed by two
bridges, being Saphan Khun Mueang Jai and
Saphan Talat Jin.

Khlong Pratu Jin is mentioned in the Royal Chronicles of Ayutthaya as being a battle front
line in 1733 (See
Khlong Pratu Khao Pluak).

On the east bank of Khlong Pratu Jin were
Wat Khun Mueang Jai and Wat Tha Jin,
while on the west bank stood
Wat Chatthan and Wat Mae Nang Muk.
