Koh Ker, located about 120km from Siem Reap town, Koh Ker was built between the 8th and 10th centuries. Koh Ker functioned briefly as the capital of the Khmer Empire between 928 and 944 A.D. when King Jayavarman IV moved the capital there from Angkor. Few people venture out to this impressive temple site as it is tucked away deep into the jungle and was largely inaccessible until recently.
Beng Mealea Temple, a sprawling jungle temple constructed in a distinctly Angkor Wat style by King Suyavarman II in the early 12th century. It preceded and may have served as a prototype for Angkor Wat. Contrary to Angkor, few carvings or bas-reliefs are evident. Today the temple is largely overrun by vegetation and the stone walls are crumbling which adds to its charm in a unique way.
