Wat Tham Phu Pha Khao is in Ban Pao Subdistrict, Nong Sung, Mukdahan, formerly known as Wat Tham Som. It is a place of dharma practice on a hill under a rock cliff. After the Taliban bombed the Buddha of Bamiyan that is more than 1600 years old, the monks and villagers at Ban Pao jointly carve a Buddha image from a rock cliff to commemorate the Lord Buddha highly respected by the people of this area. Afterward, the villagers build a concrete road to the temple, monk's houses, and rooms for meditators. Since this temple is on a cliff with limited space, there is no space for building the main hall, so the rooftop area of ​​the building is like the main hall for prayer. The Buddha image carved from the cliff is the main Buddha image of this temple. This temple is a place of meditation, it is not much well known, but to the local people, this temple is faith. A monk said most dharma practitioners are people in this area and nearby in the northeastern region.
