Prasat Tro Moung

Outside the West Gate of Angkor Thom, in the forest. It is inside the Angkor park, so you need an Angkor pass. Use the coordinates on this page.

A small sandstone temple in the forest just outside the West Gate of Angkor Thom, also known as Ta Muong. Few visitors find it. It was a hospital chapel, one of the many arogyasalas, or houses of healing, that King Jayavarman VII set up across his empire in the late 12th century.

Its founding stele, catalogued as K. 602, is dated 1108 of the Saka era, 1186 CE. Written in Sanskrit, it records the founding of the hospital with a shrine to Bhaisajyaguru, the healing Buddha, and lists the physicians and staff who served it and the grain, cloth, vessels and food given to it each year.

The sanctuary faces east. In February 2025 it was being restored: blocks numbered in chalk and sorted into rows, and a door frame standing on its moulded base. The base is richly carved, with rows of lotus petals and bands of scrolling foliage at every corner. A small shrine on the site is still given offerings.

Among the stones is a foundation deposit stone unlike the usual kind: a flat slab with its holes laid out in groups around a round centre. It is in the Foundation Stones collection, with others from across the temples.
