Mueang Fa Daet Song Yang

Mueang Fa Daet Song Yang is a Dvaravati-era moated town at Ban Sema, near Kamalasai in Kalasin province, first settled well before the 8th century and flourishing through the Dvaravati period (roughly 8th–10th century). It’s a Fine Arts Department-registered archaeological site — not a reconstructed city — so what you’re visiting is a rectangular earthwork, a double moat, and scattered carved stone, rather than standing temples.

The town’s rectangular plan is still legible on the ground: two parallel earthen ramparts, each 25–30 metres wide and 2–3 metres high, enclose a moat roughly 20 metres across that once fully surrounded the settlement. The site is best known for its sandstone sema — Buddhist boundary stones carved with scenes from the Jataka tales and the life of the Buddha — more than 100 of which have been documented across the area, some of the finest examples of Dvaravati-era stone carving found in northeastern Thailand. Within the same historical zone stands Phrathat Yakhu, a bell-shaped brick stupa and the most visually complete structure on site.

Watch out: Many of the best-preserved sema stones aren’t at the ancient-town site itself — they were relocated to the Khon Kaen National Museum for conservation and display. Come here for the earthworks, the moat, and Phrathat Yakhu; go to Khon Kaen if seeing the finest carved sema up close is the priority.

Local guides from Ban Sema village, the community built around the site, can walk you through what each earthwork and ruin represents — worth arranging in advance rather than turning up expecting an on-site info desk. The site lies within Kamalasai district, a short drive from Kalasin town along local roads; bring water, sun protection and shoes suited to uneven, grassy ground, since shade is limited across the open earthworks.
