Phnom Chisor, also called Chiso Mountain, stands above the agricultural plain of Takeo Province in southern Cambodia. The Ministry of Tourism places the temple in the Angkor-era landscape and describes the summit as a destination for its historic sanctuary and broad countryside views. The Khmer cultural-history site AMS locates it in Sla village, Roviang commune, Samraong district. The rise is visible in a largely level landscape, so reaching the temple is part of the experience rather than a short walk across a courtyard.
The sanctuary belongs to the early eleventh century and is associated with King Suryavarman I. An inscription studied by AMS records the ancient name in forms rendered as Suryaparvata or related variants, joining the Sanskrit elements for the king’s name and mountain. The temple was dedicated to Shiva, with imagery and references connecting it to other Hindu deities. These details place Phnom Chisor within a royal religious network, while the inscription also helps scholars distinguish historical names from later local explanations.
