Phnom Bok

Phnom Bok is a hill in the northeast of Eastern Baray in Cambodia, with a prasat of the same name built on it. It is one of the "trilogies of mountains", each of which has a temple with similar layout. The creation of the temple is credited to the reign of Yasovarman I: 65  between 9th and 10th centuries; established after he moved his capital to Angkor and named it Yasodharapura. The two other sister temples, named after the contiguous hills, are the Phnom Bakheng and Phnom Krom.: 113 The site of the three hills was chosen by Yashovarman I along with the Eastern Baray.
