Sambor Prei Kuk (Khmer: សំបូរព្រៃគុហ៍, Sâmbor Prey Kŭh [sɑmboː prəj kuʔ]) is an archaeological site in Cambodia located in Kampong Thom Province, 30 km (19 mi) north of Kampong Thom, the provincial capital, 176 km (109 mi) east of Angkor and 206 km (128 mi) north of Phnom Penh. The now ruined complex dates back to the Pre-Angkorian Chenla Kingdom (late 6th to 9th century), established by king Isanavarman I as central royal sanctuary and capital, known then as "Isanapura" (Khmer: ឦសានបុរៈ, Eisanbŏreă [ʔəjsaːnɓoreaʔ]). In 2017, Sambor Prei Kuk was declared a UNESCO World Heritage Site.
