Arokhayasahn (อโรคยศาล)

Thai term for the Khmer Arokyasala system. The Khmer word derives from Sanskrit, and literally means ‘school of no disease’ or ‘school of health’, related to the Thai word for disease, i.e. rohk (โรค), though is usually translated as ‘house of health’ or ‘place of healing’. It refers to a state-sponsored network of hospital sanctuaries established throughout the Khmer Empire during the reign of King Jayavarman VII (fig.) in the late 12th to early 13th centuries AD. According to inscriptions at the Ta Prohm temple (fig.), he ordered the construction of 102 such facilities across his cities, of which 30 were located in present-day Thailand, such as Koo Pohn Rakhang (fig.) in Roi Et. These institutions functioned as integrated centres of medical care, religious practice, and royal administration. Academically, the Arokyasala system is understood as a distinctive manifestation of Mahayana Buddhist state ideology, combining practical healthcare with spiritual healing. Each Arokyasala typically consisted of a standardized architectural complex, including a main sanctuary dedicated to Bhaisajyaguru, the Healing Buddha (fig.), auxiliary buildings such as a library, enclosing walls, and a gopura, i.e. a formal entrance gateway (fig.). Inscriptions indicate that these hospitals were staffed by medical personnel and supported by state resources, including medicinal supplies and ritual specialists. The system represents one of the earliest known examples of an empire-wide public healthcare network in Southeast Asia. It reflects King Jayavarman VII’s conception of kingship as compassionate and protective, in which the alleviation of suffering was both a religious duty and a political responsibility. Through the Arokyasala system, healthcare, Buddhist ethics, and imperial governance were institutionally linked, reinforcing royal authority while addressing the physical and spiritual well-being of the population. In archaeological and historical scholarship, the Arokyasala system is therefore interpreted not merely as a collection of hospitals, but as a coordinated imperial programme that materialised Mahayana Buddhist ideals within the administrative and spatial framework of the Khmer Empire.
