Isanapura
Isanapura (also known as Sambhupura, or Sambor of St'ung Sen) was the capital of the ancient kingdom of Chenla. It is located in what is now Kampong Thom Province in Cambodia. The city was founded in about 618 at Leek Sambor Kuk by King Isanavarman I.
Today, the site of old Isanapura contains the ruins of 150 temples and buildings, which are a few centuries older than that of the Khmer empire around Angkor Wat. During the Vietnam War, some of these temples were completely destroyed by US bombers. Further damage was done by vandals, dealers in old relics, and the Khmer Rouge. Many temples have been overgrown by the jungle.
