Si Thep was inscribed as a UNESCO World Heritage site in 2023 for its outstanding testimony to the cultural exchange between Dvaravati and Khmer civilizations.
The city plan features a distinct 'double-city' layout, consisting of a circular inner city and a rectangular outer city expansion.
Khao Klang Nai is believed to be the most significant monument at the site, showcasing intricate stucco decorations that date back to the 7th–8th centuries.
Excavations at the site have unearthed evidence of prehistoric human settlements dating back to the Bronze and Iron Ages, long before the Dvaravati city was established.
Prang Si Thep is oriented toward the west, which is highly unusual for Khmer-style temples that typically face east.
The site contains over 100 small scattered 'moats' and ponds that were integral to the city’s complex water management system.
Statues of the Hindu deity Surya were discovered at the site, indicating that Si Thep was an important center for Hindu-Buddhism syncretism.
Much of the site remains unexcavated, with many mounds appearing as natural hills covered in dense vegetation.
Si Thep Historical Park is a UNESCO World Heritage site featuring the remains of an ancient Dvaravati-era city dating back to the 6th–11th centuries. The site is divided into two main zones: the inner city, enclosed by a moat and earthen walls, and the outer city, which houses numerous smaller religious structures. The architecture displays a unique blend of Dvaravati, Khmer, and Indian influences, reflecting the city’s role as a major trade and cultural hub. Key structures include Khao Klang Nai, famous for its elaborate stucco reliefs of dwarfs and animals, and Prang Si Thep, a Khmer-style sanctuary built of laterite. The site covers approximately 4.7 square kilometers of archaeological landscape. A modern visitor center serves as the entry point, housing artifacts excavated from the area, including votive tablets and Hindu sculptures. The landscape is predominantly open parkland, integrating archaeological ruins with a natural forest environment.

Bring a hat, sunscreen, and plenty of water, as the majority of the ruins are in exposed, unshaded areas.
Rent a bicycle at the entrance if available to traverse the significant distances between the inner and outer city monuments efficiently.
Wear comfortable, sturdy walking shoes to navigate the uneven terrain and unpaved paths around the ruins.
Do not attempt to explore the site entirely on foot during the peak afternoon heat; avoid venturing off marked trails to prevent potential injury or damage to archaeological layers.
Dress modestly by covering shoulders and knees; remove hats and sunglasses when near religious statues; do not climb on or touch the ancient ruins.
