Study Trip

Si Thep Revisited

Saturday, 25 March 2017
Leader: Khun Somchai Na Nakhon Phanom, former archaeologist of the Fine Arts Department and Khun Somlak Charoenpot, Honorary Secretary of the Siam Society


The ancient city of Si Thep owed its importance to its strategic location on a major route connecting the Khorat Plateau through the valley of the Pasak River with the basin of the Chao Phraya. The site is therefore of considerable historical significance. It was first excavated by H.G. Quaritch Wales in 1935, and further excavations and restoration of the principal monuments have been carried out subsequently by the Fine Arts Department. The site has been cleared and now maintained as a park full of fine trees, which provides a magnificent setting for the reconstructed monuments. It covers an area of about 4.7 sq. km. and is divided into two parts known as the Inner City and the Outer City. In the 6th century A.D., Si Thep appears to have been ruled by the Mons, who built the Inner City. By the 9th century A.D., it had fallen under the rule of the Khmers, who constructed the Outer City and remained at Si Thep until the 12th century, when the city was abandoned. The Outer City is roughly elliptical in shape and measures about 4 x 1.5 km., it was surrounded by a wall and moat and had seven entrances. This ancient city located in Phetchabun province and about 240 km. from Bangkok.

There are many important sites in this old city. The religious sculptures of Si Thep consists of a number of Buddhist images, both Mahayana and Theravada. The Hindu Khmer monuments are built in the early Angkor Wat style.
