Phra That Ruen Rong is a traditional art-style stupa located at Wat Ban Chrang Ruen in the Yha Plong District of Muang Si Sa Ket, Si Sa Ket Province. This stupa showcases the folk art styles of four ethnic groups: the Suai, Khmer, Lao, and Yeo. Construction began in 1981 under the guidance of Luang Pu Thamma Pithaksa. Standing at 49 meters tall, it features a square base measuring 30 meters on each side and is divided into six tiers. Surrounding Phra That Ruen Rong, the area has been beautifully decorated with replicas of mystical sculptures and models depicting significant traditions and ceremonies of the Isaan people. Additionally, there are designated spaces for visitors to contribute by making donations, worshiping sacred objects, and purchasing souvenirs. All proceeds are allocated towards the ongoing maintenance and development of Phra That Ruen Rong.
