Prang Song Phi Nong

Prang Song Phi Nong is a pair of Khmer-style brick prangs located in Si Thep Historical Park, Si Thep District, Phetchabun Province. Situated outside the inner ancient town moat, the twin towers are among the most significant monuments of the Si Thep ancient town, a UNESCO World Heritage Site. Built in the 11th-12th century in Bayon style, they reflect the transition from Hindu to Mahayana Buddhist use.

Visitors can expect to see two adjacent laterite and brick prangs standing on a shared laterite base, surrounded by open grassy grounds within Si Thep Historical Park. The larger prang is more complete with a porch and sandstone lintel and colonnette details, while the smaller prang is more ruined. The site is outdoors with information boards, pathways, and views of the ancient town landscape. It is explored on foot as part of a park circuit.

Prang Song Phi Nong was constructed in the 11th-12th century during the Khmer period, in the Bayon architectural style associated with King Jayavarman VII. It was originally a Hindu shrine and later adapted for Mahayana Buddhism. It is part of the ancient town of Si Thep, which flourished from the Dvaravati period (6th-11th century) through the Khmer period and is now recognized as a UNESCO World Heritage Site inscribed in 2023.

The twin prangs illustrate Khmer religious architecture and the cultural layering of Si Thep, where Dvaravati, Hindu and Buddhist traditions overlapped. The site is valued for its artistic elements such as lintels and colonnettes and remains an important place for understanding the spread of Khmer culture into central Thailand.
