Wat Wong Jak is located west of the main island, near the Chao Phraya River. It was once situated within the Khlong Maha Nak defensive system of canals. For the most part, this ruin consists of a brick mound; however, a small shrine has been constructed on site to protect the remains of several Buddha images. One image includes a head that has survived. A large number of bricks, pottery shards, and roof tiles are scattered around this site. Nevertheless, there are no surviving chedi, sermon halls, or boundary walls. The area is prone to heavy flooding, which has taken its toll on the former monastery.
There is not much history known about this ruin. It first appears on the Phraya Boran Rachathanin map drafted in 1926. Charnvit Kasetsiri and Michael Wright point out that a Lao settlement was located in this area. They trapped and sold birds that were later released for merit [1]. However, there is no clear connection between Wat Wong Jak and a Laotian community. The impoverished neighborhood remains Buddhist for now; however Muslim populations are rapidly growing in the vicinity.
