Located in Kulen District, Preah Vihear Province, Koh Ker once served as the Khmer capital during the Angkor period. The area is home to numerous ancient temples left by Khmer ancestors. Among them, Pram Temple stands out for its refined architecture, rising gracefully amid dense forest and attracting great interest from visitors.
Pram Temple covers an area of over 2,000 square meters, enclosed by walls measuring 42 meters wide and 54 meters long. Built in the Koh Ker style during the reign of King Jayavarman IV in the early 10th century, the complex features three towers facing east and two libraries facing west, dedicated to Brahmanism.
