About
Koh Ker is an archaeological site in Preah Vihear Province, in northern Cambodia. It was the capital of the Khmer Empire for a short period, from 928 to 944 CE, and its ruins are spread across a wide area of forest rather than gathered into a single compact complex. The site is also known as the Koh Ker Temple Complex, and under the name Chok Gargyar it appears in the historical record of the city.
What you will see
The most striking structure is Prasat Thom, a stepped pyramid temple with seven tiers. Climbing its terraces gives a clear sense of how the monument was built and how it rises above the surrounding trees. Beyond it, numerous other temple ruins lie scattered across the old city grounds, so a visit often becomes a slow walk from one site to the next, with long stretches of forest in between.
What kind of visit it makes
- A half-day or full-day outing for those interested in Khmer architecture and early Angkorian history.
- A quieter alternative to the more heavily visited temples of the Angkor region, given its distance from them.
- A journey best planned with the terrain in mind, since the ruins are spread out and paths between them can be uneven.
Getting oriented
Koh Ker lies in Preah Vihear Province, so the visit is usually made as a trip into the north of Cambodia rather than as a stop in a city. Visitors should check current access arrangements and local conditions before setting out. The site was recently inscribed as a UNESCO World Heritage Site in 2023, which reflects its growing standing among the country's heritage places.
