Sambor Prei Kuk became Cambodia’s third UNESCO World Heritage Site in 2017. A vast complex of more than 100 Hindu temples that even predates Cambodia’s tourism jewel of Angkor, this majestic temple site is located about 30km from Kampong Thom’s provincial capital. The site was originally called Isanapura and was the capital of the ancient kingdom of Upper Chenla during the early 7th century. Later, it was the site of the Khmer capital, before Angkor became the seat of the empire.
