The stupa of this temple is another archaeological site believed to have been constructed around the same period as the stupa at Wat Phra Borom That Chaiya, which is estimated to have been built during the 14th-15th Buddhist centuries. Unfortunately, it has been abandoned for a long time and is now in a state of disrepair, leaving only remnants of bricks and a crumbling foundation. However, between 1981 and 1984, the Department of Fine Arts undertook restoration work, allowing us to visualize the shape of the stupa more clearly and distinctly. Location: It is situated in Ban Wat Long, right next to Wat Rattanaram.
