The archeological site was discovered in 1969 by the ethologist Jean Boulbet but further exploration of the site was curtailed due to the Cambodian Civil War until 1989 when the site was safe to visit.
The carvings were started during the reign of King Suryavarman I and ended with the reign of King Udayadityavarman II, these two kings ruling between the 11th and 12th centuries.. The 1,000 lingas were attributed to a minister of Suryavarman I during the 11th century and these were carved by hermits living in the area.
The sculptures carved in the river bed and banks depict many Hindu mythological scenes and symbols and when the water level decreases there are also inscriptions which get exposed. The common theme of these sculptures is about creation as defined in Hindu mythology with Lord Vishnu lying on a serpent in a reclining pose on the ocean of milk, the lotus flower emerging from Vishnu’s navel which bears the god Brahma, the creator.
