Neak Pean "The entwined serpents" is built on an artificial island with a Buddhist temple and was constructed during the reign of King Jayavarman VII. The temple and lake represent Anavatapta - a mythical lake in the Himalayas - with waters that are believe to cure illnesses so Neak Pean was set up for medical purposes. The ancients believed that going into the pools would cure diseases based on the ancient Hindu belief of balance. Four connected pools represent Water, Earth, Fire and Wind. The stone statues in pavilions are meant to represent the heads of the Four Great Animals.
