Krol Ko

Krol Ko at Angkor, Cambodia, is a Buddhist temple built at the end of the 12th century under the rule of Jayavarman VII, in his Bayon architectural style. It is north of Neak Pean. The name 'Krol Ko' is a modern term meaning 'The Park of the Oxen' and likely has no connection to its historical use.

While speculative, it may have served as a chapel at a hospital site, as its layout is identical to the four hospital chapels found outside Angkor Thom. Placement of a hospital close to Neak Pean would have made sense as Neak Pean was constructed as a representation of the waters of the mythical lake Anavatapta, which were thought to help the attainment of salvation amongst those deceased. Seven of the temple pediments at Krol Ko feature Lokeshvara, a boddhisattva who, in Khmer Buddhist belief, was entrusted with healing powers.
