O Pha-ong Temple (Phnom Kulen)

Also recorded as Aur Pha On, O Phaong, Neak Ta, and Andong Temple. Prasat O Pha-ong is a tall square brick temple on a raised brick terrace. It opens to the east and features three false floors, decreasing in size with each step up, also featuring “mini-prasats” at each corner. Rather than carved elements, it uses the brickwork itself to add decoration to its eaves and basement although it may have also been rendered in stucco with further decoration that we don’t see today. Up high, some remnants of a white coating can still be seen.

The site also featured a brick wall around the perimeter which some parts can still be seen today and likely once had an entrance gopura on the eastern side.
