Koh Ker temple is a remote archaeological site in northern Cambodia about 120 kilometres (75 mi) away from Siem Reap and the ancient site of Angkor, It is a jungle filled region that is sparsely populated. More than 180 sanctuaries were found in a protected area of 81 square kilometres, Only about two dozen monuments can be visited by tourists because most of the sanctuaries are hidden in the forest and the whole area is not fully demined.
