Cambodia’s Sambor Prei Kuk archaeological site has been named as a World Heritage site by the United Nations Educational, Scientific and Cultural Organization (Unesco), making it the country’s third. Located in Kampong Thom province, the site includes ruins from Ishanapura, the walled capital of the Chenla Empire which encompassed parts of Cambodia, Laos, Thailand and Vietnam. Built between the late 6th and 7th centuries, the site predates the Angkor Wat complex and played an important role in the evolution of Cambodian architecture. The architectural style “are true masterpieces,” according to Unesco.
