Originally called Mueang Aphai Sali, Si Thep Historical Park contains the ruins of ancient Phetchabun, which are believed to have been built during the rise of the Khmer Empire. The influence of Khmer and Dvaravati architecture on the more than 70 ancient remains is clear.
Within a moat and two city walls are perfect examples of Khmer architecture, including the brick and laterite Prang Si Thep, the typically Khmer religious layout and design of Prang Song Phi Nong, and Khao Khlang Nai Ancient Monument, believed to be a weaponry and treasure store.
Around its base are decorative stucco sculptures of people and animals in the Dvaravati style. It really is a must - see attraction for visitors to Phetchabun.
Si Thep District, open daily from 8.30 a.m. to 6.30 p.m. Tel. +668 8858 1290
