Sema ancient remains
Mueeang Sema Historical Site is in Tambon Sema, about 37 kilometres from the city. From Amphoe Sung Noen go across Lam Takhong River past Ban Hin Tang to Sema 4 kilometres away. The Sema city plan is egg-shaped and is 3 kilometres wide and 4 kilometres long. You can still see evidence of city moats and some earth walls. The city flourished during the Dvaravati period and was built around the 12th Buddhist century. It grew until the 16th-17th Buddhist centuries when it came under Khmer influence. In the area are ruins made of laterite and sandstone and many artefacts have been unearthed here. The most interesting one is the reclining sandstone Buddha image and an old religious relic that is now in Wat Thammachak Semaram.
