Prang Si Thep

Prang Si Thep is the principal Khmer-style prang within Si Thep Historical Park in Si Thep District, Phetchabun Province, central Thailand. Located in the inner ancient town, it is the most prominent monument of the park and part of The Ancient Town of Si Thep UNESCO World Heritage Site inscribed in 2023. Built in the 11th-12th century in Baphuon style, it reflects Hindu influence later adapted for Buddhist use.

Visitors can expect a well-preserved laterite and sandstone prang with a single tower on a high base, surrounded by a laterite enclosure wall and remains of ancillary structures. The site is set within the landscaped Si Thep Historical Park with open grassy areas, ancient moats and walkways. Visitors can walk around the prang, view stucco and lintel details, take photographs, and explore the inner town area on foot or by bicycle.

Prang Si Thep was constructed in the 11th-12th century during Khmer influence over the Si Thep ancient town, which flourished from the Dvaravati period (6th-11th century). Built in Baphuon style as a Hindu shrine and later used for Mahayana Buddhism, it represents the peak of Khmer architecture at Si Thep. The ancient town of Si Thep, including Prang Si Thep, was inscribed as UNESCO World Heritage Site in 2023 as The Ancient Town of Si Thep and its Associated Dvaravati Monuments.

The prang reflects the religious transition from Hinduism to Buddhism in central Thailand and is a key example of Khmer religious architecture outside the Angkor region. It remains an important archaeological and educational site illustrating Dvaravati and Khmer cultural heritage, managed by the Fine Arts Department.
