Prasat Phanom Rung is a Khmer sanctuary on Phanom Rung Mountain in Buriram. Its long raised approach, aligned buildings and hilltop position make the route itself part of the architecture.
The Fine Arts Department's historical account identifies Phanom Rung as a Hindu sanctuary associated with Shaivism and the worship of Shiva. Inscriptions and surviving structures show that the complex grew over time and served as a religious centre with land and communities attached to it.
The sanctuary is arranged on a straight axis toward the main prasat, with gateways, terraces and rising ground drawing visitors toward the shrine. The site was registered as a national historic monument in 1935, reconstructed using anastylosis from 1971 and opened as a historical park in 1988.
