Koh Ker is an ancient capital city of the Khmer empire, located about 3 hours away from Siem Reap in northern Cambodia. This old city is home to many temples, buildings and other monuments, and was a thriving town home to over 20,000 people. Surrounded by thick jungles, many of these monuments have been invaded by forests.
Due to its remote location amidst this canopy, Koh Ker's ruins are well-preserved and have avoided invasion and destruction. It is surprisingly not well-known to the tourists who bypass Koh Ker enroute Angkor. The city of Koh Ker is known for its pyramid tower structure Prasat Thom or Prang. It looks similar to a Mayan civilization monument at 36 metres high, with their seven tiers offering splendid views of the surrounding jungle.
