This is a Naga that has just been dug out from the ground in Beng Mealea temple. It is very well preserved. 
Beng Mealea is a Hindu temple which was built in the 12th century by the king Suryavarman I. This temple is located in the remote area covered by the jungle, near the Mount Kulen (the stone quarry) that is about 60km from Siem Reap town.
