Maeung Fa Daet Song Yang is a significant moated archaeological site in Northeast Thailand along the Pao River. The site is located in the Kamalasai district, Kalasin province on the Khorat Plateau with the Sakhon Nakhon basin to the north, and the Chi River system to the south. The site on Muang Fa Daed was also an excellent location for trade and transportation due to its proximity to multiple waterways. This site shows evidence of a large-scale Buddhist community and is often associated with the Davaravati culture based on the multitude of artifacts and features found at the site. The site was first excavated in 1968 and later by Phasook Indrawood in 1991, who dug nine test pits and found two phases of occupation. This region also indicated that agriculture was a large part of the lifestyle here. The site was thought to have been founded by Chao Fa Ra-ngum in 621 AD.
