WAT LAT (วัดลาด)
Wat  Lat (also known as Chaiyaphum and Chaiya Bhumi) is located south of the
former
Pa Than bridge and the Chedi Ay and Chedi Yi memorials. The area is known as
the Pratu Chai District, and it is the location of an old market site that sold wood
charcoal for fires - hence, the temple's former name (Temple of the Charcoal Bridge).

The ground plan or base of the brick chedi is square. The bell-shaped dome (anda) and
cube-shaped reliquary (harmika) are badly damaged, while the nine-tiered umbrella roof
(chatra) is in slightly better shape. The main building with its entrance to the east was
likely a sermon hall, as no traces of boundary stones were found on the site. Specific
here is that the brick building was surrounded by a series of chedi, which (like the
boundary stones) had the function of warding off evil spirits. A fairly large face of a
Buddha image has survived. It is perched in the sermon hall next to stacks of debris from
other Buddha images. Traces of the monastery's outer wall are not visible.

The temple's main historic relevance concerns a battle for royal succession in 1424. King
Intharaja I had three sons, named according to the old numerical system (Ay = first, Yi =
second and Sam = third). On their father's death, in 1424, the two elder sons, Phraya
Ay living in Suphanburi, and Phraya Yi leaving in Phraek Siracha, fought for their father's
throne in Ayutthaya. Ay and his adherents were stationed at
Wat Chai at the Coconut
grove (Pa Maphrao), while Yi and his people held up at Wat Chaiyaphum. Both princes
engaged each other in personal combat, mounted on elephant, on or near the "charcoal
forest" bridge (Saphan Pa Than) - just north of the temple. Both were severely wounded
and died from combat wounds. The youngest brother, Phraya Sam, who was living in
Chainat, was then proclaimed King under the title of Boromaracha II.

This deserted monastery is most often covered in thick vegetation today, and packs of
biting dogs live nearby; therefore, it is better to visit the site with caution and to enter via
Ho Ratanachai Rd.

Addendum

Wat Lat or the "Inclined Monastery" is indicated on a map drafted in the mid-19th
century and on Phraya Boran Rachathanin's map of 1926.

Based on an overlay made of the mid-19th century map, the position of Wat Lat is
located much more south compared with the ruin what we call today Wat Lat; and the
monastery stands more or less where Phraya Boran Rachathanin (PBR) situates
Wat Pet
on his 1926 map. The mid-19th century map indicates the existence of a prang on an
indented square base, but on the present position of Wat Lat we find a chedi.

On the position where PBR indicates Wat Lat, we find on the mid-19th century map, a
monastery called
Wat Kut. This monastery is indicated with a chedi. It could be an
indication that the Wat Lat of today was called Wat Kut two centuries ago.

It is obvious that there were different monastic structures in this area and their
denomination remains unfortunately a bit of guess work.

Historical data about Wat Lat and its construction are not known.

Site view of Wat Lat shortly after receding of the flood which hit the Historic City of
Ayutthaya and its Historical Park in the evening of 7 October 2011. Pictures were taken on
28 November, three weeks after the much announced Ayutthaya Clean-up Day. The site was
a garbage belt and the structures were completely overgrown. This site needs urgent
restoration as part of the Historic City of Ayutthaya.
