Prasat Prei Monti

Prasat Prei Monti (Khmer: ប្រាសាទ​ព្រៃមន្ទីរ) is an early Angkorian site in the Roluos group of monuments near Siem Reap, Cambodia. Archaeological evidence identifies it as the royal palace precinct of Hariharālaya, the first Angkorian capital under King Indravarman I (r. 877–889 CE). The site consists of a large moated enclosure with three brick towers on a sandstone platform and traces of wooden structures. Excavations have also uncovered some of the earliest imported ceramics in Angkor, indicating Cambodia’s integration into long-distance trade networks during the ninth century. Remote sensing has shown that Prei Monti was part of Hariharālaya’s water-management system, linking it to the Indratataka reservoir and the wider hydraulic city.
