Koh Ker Heritage Festival in Koh Ker
Koh Ker's heritage-festival profile centers on a specific milestone, its UNESCO World Heritage inscription on 17 September 2023, rather than on a confirmed, separately recurring annual celebration. The tenth-century former royal capital, home to the striking seven-tiered Prasat Thom pyramid, is a genuine major heritage site, but no consistent yearly festival distinct from UNESCO-anniversary commemorations was confirmed in research.
Koh Ker earned its heritage-festival reputation less from an annual public celebration and more from a specific milestone: its inscription onto the UNESCO World Heritage List on 17 September 2023, at the 45th session of the World Heritage Committee held in Riyadh.
