Prasat Ta Muean Thom is located on a line of the Banthat mountains facing south. Built in laterite and sandstone, it is a Hindu monastery of the Sawai sect respecting Phra Shiva, the highest god. It was built in Baphuan Art style in the 11th century.
Currently there is access to Prasat Ta Muean Thom during restricted hours. This temple lies in disputed territory along the Thai/Cambodia border, a situation that awaits a decision by the United Nations Border Commission. In the meantime after recent tension on the border, there is an agreed joint occupation by representatives of the Thai and Cambodian armies.
During the Khmer Rouge regime, this borderland was raided for its precious carvings and art treasures. The border post here serves as both maintenance of the peace and protector of the ruin. Solders of both armies are available to show visitors around with clear knowledge of this important site.
