Prasat Chom Phra was a hospital or religious site of the hospital which is one of the 102 hospitals which King Jayavarman VII commissioned in the 18th Buddhist century due to the fact that he was a Buddhist devout of the Mahayana order and he also encouraged his subjects to follow suit. This changed the architectural aspect of the Khmer culture which used to be grand structures as per the principle in Hinduism construction to become a community service base architecture for the well being of his subjects according to Buddhist principles.
From all evidence and the inscriptions in all the hospitals it was found that King Jayavarman VII commissioned hospitals nationwide with the governors of each city made responsible and also to appoint medical personnel and procure medication to cater to the population’s ailments.

The whole complex is surrounded by a low laterite wall rectangle in shape with an area of 21.60 x 45 m. and to the east is a gateway in the shape of a cross with a window next to it.
