Bakong Temple is part of the original Hariharalaya (Jayavarman II's 8th century capital) group of Angkor temples located outside of Siem Reap in the Roluos area, hence the modern name for these temples, the Roluos Group. Bakong is the largest, and was the state temple of Indravarman I, and was dedicated to the Hindu god Shiva. It is also the first significant temple-mountain built of sandstone.
When it comes to exploring the temple, you will be greeted at the entrance to the temple (second enclosure, you will have taken the road to arrive here), by seven headed nagas over the causeway which crosses the moat - a naga bridge almost as their bodies lay on the ground. On the east side of the outer enclosure are two long halls with octagonal columns and deep lintels.
