The Ancient City in Samut Prakan (Muang Boran)
Phra That Ya Khu Chedi lies within the old walls of the ancient town of Fa Daed Sung Yang in Kalasin. The unique eight-sided chedi is quite unlike any other chedi in Thailand.
The Chedi was built by the local people to mark the place where they held meetings and performed communal acts of merit. It is believed that the Chedi was built on the site of a much earlier monument which dated back to the Dvaravati period.
