Ban Sema, a village about 20 km (12 mi.) west of Kalasin, near Yang Talat, is a particularly interesting place to see since in the 9th to 11th c. it was the site of the Dvaravati city of Muang Fa Daed. This was surrounded by two moats where important finds have been made of items from the period between the 6th and 13th c., one of great
significance in the development of Thai art and culture. There is an interesting mix of local art and that of neighboring peoples, including the Khmer, and this is most notable in the semas, the boundary stones denoting the consecrated part of a temple. Two particularly fine ones have beautifully carved bas-reliefs showing the Buddha being worshipped by the Royal couple (this is kept in one of the monastery buildings of the Wat Po Chai Semaran), or illustrating Buddha's return to his family (Museum of Khon Kaen, see entry). More of these boundary stones are on display in the courtyard of the wat.
