Phnom Bakheng, the state temple of the first Khmer capital in the Angkor region, survives as one of the world’s greatest architectural treasures. The Temple of Phnom Bakheng was constructed between the late ninth and the early tenth century by Yasovarman I as the centerpiece of his new capital, known as Yasodharapura. It was abandoned only a few decades after its construction, but its privileged hilltop location makes it unique among the temples of Angkor.
