Muang in Thai translates as ‘city’. Muang Sema is an archaeological site of some importance as it has provided objects for study and research into not only local history but for the country as a whole.
Located in tambon Sema, Muang Sema comprises a large enclosure measuring 3 km. by 5km. From recent excavations, it is known that occupation of the site began in the 7th to 8th Century. Cultural materials have close similarities with those from Dvaravati sites in central Thailand. The occupation continued into the Khmer period (10th -13th centuries A.D.). An inscription from Bor-E-Ka sanctuary at Muang Sema mentions the overlord named Sri Canasa and the date 868 A.D. Another inscription was also found here which mentions the Khmer King Jayavaraman V who ruled in Angkor from 968 to 1001. The site consists of 7 numbered monuments recorded by the Fine Arts Department. The objects found on this site confirm that this was a Buddhist site with later Hindu influence. The objects are now in local and national museums.
