Koh Ker complex
Koh Ker could be described Cambodia’s forgotten capital. Tucked away in the forests of Preah Vihear province in the north of the country, Koh Ker was briefly the Khmer capital during the reign of Jayavarman IV (928-942 CE), who moved here from Angkor after seizing the throne from a rival. The captial was moved back to Angkor in 944 by his son Harshavarman I, who was his successor.
The Koh Ker area is home to well over 100 temples, with 30 major structures. The principal structure at Koh Ker is Prasat Thom, a 35m high sandstone pyramid with seven levels. The top of the pyramid rewards with spectacular views of Mt Kulen to the south and the Dangrek mountains along the Thai border to the north.
