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