Main image

Wat Ounalom is a principal Buddhist temple complex in central Phnom Penh that functions as the national seat of Cambodia’s Buddhist monastic order. It is one of the most important religious sites in the city and is located close to the royal and riverside precincts.

The complex includes a central stupa, assembly halls and monastic buildings used for worship, ceremonies and religious administration. The site serves both as a place of ritual and as the administrative center for the Cambodian sangha, with active monastic communities and education functions.

Several buildings on the site date back many centuries and the compound has been maintained as a continuous center of Cambodian Buddhism despite periods of damage and repair in the 20th century. Restoration and conservation work has taken place periodically to preserve the complex.

The temple sits on flat ground near the banks of the Tonle Sap and Mekong riverfront in Phnom Penh, within walking distance of the Royal Palace and central hotel and government areas.

  • Location: Sits near the Royal Palace and the riverfront road Sisowath Quay, making it centrally accessible from Phnom Penh's riverfront area.
