There is a holy well which was dug up at the same time of Phra That Choeng Chum. At first, there was still water since it was the ending spot of the underground tunnel which flowed from Phuphan mountain range through
the north office center and the heart of Wat Nue. It was called “Phu Nam Sod” or “Phu Nam Lod”. Then it flowed to Sra Pang Thong pond in Somdej Phra Sri Nakarin park, next to the temple. When the water decreased, people built the wall to avoid soil erosion. In the past, people used this water from the well to use in important sacred religious ceremonies.
