Khao Khlang Nok

Khao Khlang Nok is a large Dvaravati-period Buddhist stupa located just outside the ancient walled town of Si Thep in Si Thep District, Phetchabun Province, Thailand. Part of Si Thep Historical Park and the UNESCO World Heritage Site 'The Ancient Town of Si Thep and its Associated Dvaravati Monuments' inscribed in 2023, it dates to the 7th-8th century. Built of laterite and brick, it is regarded as the largest Dvaravati stupa in Thailand and a key example of early Buddhist architecture.

Visitors can expect a large, restored laterite and brick stupa standing on an open plain about 2 km north of the Si Thep inner town. The monument has a square laterite base with pilasters, a brick dome and surrounding walkway. The site is outdoors with gravel paths, information boards and open views of the surrounding fields. Visitors can walk around the base, view architectural details and take photographs. It is typically visited as part of a tour of Si Thep Historical Park.

Khao Khlang Nok is a major Dvaravati monument dated to the 7th-8th century, associated with the ancient town of Si Thep, one of the largest and most important Dvaravati settlements in central Thailand. The stupa reflects early Theravada Buddhist architecture and urban planning of the Dvaravati period. Excavated and conserved by the Fine Arts Department, it forms part of the Si Thep Historical Park inscribed as a UNESCO World Heritage Site in 2023.

The stupa is a significant example of Dvaravati Buddhist art and architecture, representing the spread of Buddhism in central Thailand during the first millennium. It remains a cultural and educational site illustrating early Buddhist religious practices, construction techniques using laterite and brick, and the heritage of the Si Thep ancient town.
