Neak Pean is a late 12th century water temple built during the reign of King Jayavarman VII, set alone in the middle of a vast reservoir near Angkor. Unlike most Khmer temples, it was conceived around water as a force of healing and purification, believed to restore balance and relieve illness through sacred contact. Entwined naga serpents wrap tightly around its base, binding the unique shrine into a single symbolic form, from which the temple takes its name.
