Roluos Group
Three of the oldest Angkorian temples belong to this site, which is situated about 13 km east of Siem Reap: Bakong (the first temple pyramid built by an Angkorian emperor), Preah Ko (the ‘Sacred Ox’, consisting of six towers, was the first built temple of the ancient capital city of Hariharalaya) and Lolei (King Yasovarman I dedicated this temple to his father and other relatives).
