Phnom Bok is northeast of East Baray. On this mountain stands a sandstone temple with three towers. It was built in the late 9th and early 10th centuries during the reign of King Yasovarman I. The mountain is called Phnom Bok, but no one knows from where the name came.

Near the foot of Phnom Bok is Top temple. Heavily damages over time, this temple was made of brick. Its original name was Trapiang Chambok. Another temple at the foot of Phnom Bok is called Leak Neang. It is made of brick and has three towers, but only one is still in good conditioin. There is also a pond in front of the temple. The temple was once called Chhuk Temple, but it now is known as Leak Neang Temple.
