Lonely Planet review
Koh Ker is one of the least-studied temple areas from the Angkorian period. Louis Delaporte visited in 1880 during his extensive investigations into Angkorian temples. It was surveyed in 1921 by the great Henri Parmentier for an article in the Bulletin de l'École d'Extrême Orient, but no restoration work was ever undertaken here. Archaeological surveys were carried out by Cambodian teams in the 1950s and 1960s.
But all records vanished during the destruction of the 1970s, helping to preserve this complex as something of an enigma. Several of the most impressive pieces in the National Museum in Phnom Penh come from Koh Ker, including the huge garuda (mythical half-man, half-bird creature) that greets visitors in the entrance hall and a unique carving depicting a pair of wrestling monkey-kings.
