An aerial view of "Prasat Baan Panna" in Sakon Nakhon Province illustrates the layout of an ancient Khmer-style hospital (Arokayasala) enclosed by a glass wall. Inside, you'll find a central prang (tower), a library, and a laterite-lined pond located in the northeast quadrant, set against a backdrop of agricultural land. This arrangement clearly demonstrates the cosmological beliefs and healthcare practices prevalent during the reign of King Jayavarman VII.
