Koh Ker is an anomaly in Khmer history. In 928, Jayavarman IV — the uncle of the deceased king and a claimant to the throne — decided to leave Angkor and establish his own capital 120 km northeast, in the middle of the forest. He named it Chok Gargyar (or Lingapura, "the city of liṅga"). For sixteen years, he had over 180 monuments constructed at a frantic pace in less than two decades. Then his successor returned to Angkor, and Koh Ker was gradually abandoned.
The result today is a remarkable archaeological complex, rarely visited, where vegetation has overtaken the temples but not to the point of making them illegible. And at the center: Prasat Thom, the pyramid.
Prasat Thom — The Khmer Pyramid
This is the main attraction of the site — and one of the most impressive structures of Khmer heritage. Prasat Thom is a seven-tiered pyramid made of pink-orange sandstone, standing 35 meters tall, built according to the model of the mountain temple symbolizing Mount Meru. At the top, a massive liṅga in sandstone (a phallus symbolizing Śiva) was found — it is now housed in the National Museum of Phnom Penh.
The climb to the summit is one of the highlights of a trip to Cambodia. Seven levels to ascend, each step a bit steep, leading to a terrace where the view extends over a sea of forest as far as the eye can see. In the absence of skyscrapers or mountains, Prasat Thom offers one of the few elevated views available in this flat region of Cambodia.
🔍 Koh Ker art: a style apart
Art from Koh Ker's brief period (928–944) is so distinct it has its own name: the Koh Ker style. Its statues — especially Dvarapalas (guardians) and dancers — are known for often monumental size (some over 3 metres), dynamism and unusual expressiveness in Khmer art. Many were looted and are in Western museums; a restitution programme is under way.
The Other Temples of the Site
Aside from Prasat Thom, the Koh Ker complex has about twenty main temples scattered over several kilometers. The most interesting include:
- Prasat Krachap ("the hat tower") — an isolated tower with a liṅga and well-preserved bas-reliefs
- Prasat Neang Khmau ("the black lady tower") — a laterite temple with traces of ancient paint on the interior walls
- Prasat Pram ("the five towers") — five towers in a line, overtaken by the roots of fig trees in a style reminiscent of Ta Prohm
- Prasat Bram — a group of partially collapsed towers with interesting sculpted pediments
- The Grand Baray of Koh Ker — a royal reservoir measuring 1,200 meters by 550 meters, now partially dried up but visible from the road

How to Get There
Koh Ker is 120 km from Siem Reap, on a now-paved road. By van or car: about 1 hour and 45 minutes. The site is often combined with Beng Mealea in the same day (Beng Mealea in the morning, Koh Ker in the afternoon). Tuk-tuks are not recommended for this distance.
Organized tours from Siem Reap offer this Koh Ker + Beng Mealea combination with air-conditioned van transport, a guide, and lunch included. This is by far the most comfortable option.
Air-conditioned van day trip covering both remote temples, English-speaking guide. From about 45 USD per person.
