The Chedi, the Ubosot of the Minor Wife, and the Ubosot of the Main Wife at Wat Khao Bandai It are important structures within the temple. The Chedi enshrines sacred relics or Buddha relics, the Ubosot of the Main Wife serves as the primary hall for religious ceremonies, and the Ubosot of the Minor Wife is a smaller, separate hall. All three reflect traditional Thai architecture and Buddhist beliefs.
