The monuments of Roluos, which served as Indravarman l’s (r 877-89) capital, Hariharalaya, are among the earliest large, permanent temples built by the Khmers and mark the beginning of the age of Khmer classical art. Before the construction of Roluos, generally only lighter (and less-durable) construction materials such as brick were employed.
The temples can be found 13km east of Siem Reap along NH6 near the modern-day town of Roluos: Preah Ko is 600m south of NH6, while Bakong is 1.5km south of the highway. There are contemporary Buddhist monasteries at both Bakong and Lolei. For those who aren’t traveling much beyond Siem Reap and Phnom Penh, it may be worth venturing into the genuine Cambodian town of Roluos for a refreshing drink.
PREAH KO
Preah Ko was erected by Indravarman I in the late 9th century, and was dedicated to Shiva. The six prasat (stone halls), aligned in two rows and decorated with carved sandstone and plaster reliefs, face east; the central tower of the front row is a great deal larger than the other towers. Preah Ko has some of the best surviving examples of plasterwork seen at Angkor and is currently under restoration by a German team. There are elaborate inscriptions in the ancient Hindu language of Sanskrit on the doorposts of each tower.
