 As later kings (whose residence was not in Koh Ker) changed from Hinduism to Buddhism they gave orders to make the necessary adjustments at their temples.Because of its remoteness, the sanctuaries at Koh Ker were spared from these interventions.Several inscriptions were found which mention Koh Ker as capital of the empire in Siem Reap, Battambang, Takeo and Kampong Cham (city).
