Prasat Bakong is the most impressive of the Roluos Group of temple complexes, located east of Siem Reap. The Rolous Group was the former capital of the Khmer Empire prior to the relocation to Angkor and Prasat Bakong was the "Angkor Wat" of the earlier period. In fact, Prasat Bakong shares many architectural similarities with Angkor Wat, but on a reduced scale. The Roluos Group is well worth some attention if your itinerary permits. The group consists of a handful of small to medium temple complexes that can be seen in about a half day. The Roluos temples are pre-Angkorian and allow the visitor to see the evolution of architectural styles and religious themes from early to late. While your there, be sure to purchase some refreshments from the local roadside vendors that don't see nearly as many tourists as the popular Angkor area.
