UNESCO: ✅ World Heritage Site
A remote former capital with a dramatic 36-meter stepped pyramid — Cambodia's newest UNESCO World Heritage Site (2023).
Koh Ker served as the capital of the Khmer Empire for a brief but intense period from 928 to 944 AD under King Jayavarman IV. The most striking structure is Prasat Thom (also called Prang), a 36-meter-high, seven-tiered stepped pyramid that is the tallest pyramid structure in Cambodia and one of the tallest in Southeast Asia. Unlike other Angkorian state temples that are square, the Koh Ker pyramid has a unique rectangular base. The site contains over 180 sanctuaries spread across an area of 81 hectares, many still unrestored and engulfed by forest. In September 2023, Koh Ker was inscribed as a UNESCO World Heritage Site, recognizing its outstanding universal value. The remote location — 120 km from Siem Reap — means visitors who make the journey are rewarded with an almost solitary temple experience.
