Wat Chamadevi, or as the local people call it Wat Ku Kut, is located on Chamadevi Road, Tambon Nai Mueang. It was built in 755 in the Lavo style. The Chedi is a square structure similar to Bodhgaya in India. Each side has a standing Buddha image in the posture of giving blessings. The ashes of Queen Chamadevi, the first monarch of the Hariphunchai Kingdom, are enshrined within the Chedi. According to legend, Chao Anantayot and Chao Mahantayot, the sons of Queen Chamadevi, built it in the year 755 to enshrine the ashes of the Queen. It was originally wrapped in gold, but this disappeared over time. The local people call it “Ku Kut” or as it is known officially as “Phra Chedi Suwan Changkot”. In addition to this, there is Rattana Chedi, which is located to the right of Wihan Phraya Sanphasit and built in the 12th century. The lowest base is an octagon with a diameter of 4.40 metres and a height of 11.50 metres. The chedi is a square shape, and each square is pierced into an alcove to enshrine a standing Buddha image made of brick and mortar.
