Located in the central zone of the Angkor Archaeological Park, Ta Keo is a pyramid on five levels, where the upper five tiers rise to a height of more than 50 meters. It was built between the late 10th and early 11th centuries. Chinese experts have been working with local colleagues for 8 years to restore these invaluable treasures of Cambodia. The Ta Keo pyramid has been revived through the efforts of both Chinese and Cambodian archaeological experts.
