On the first day, the circuit proposes a visit of five monuments related to the cult of Shiva alone and Shiva in the Brahmanical trinity (Brahma-Shiva-Vishnu).
Bakong, Preah Ko and Lolei are generally known as temples of Roluos Group. They are situated about 15 kilometers East of Siem Reap town. Preah Ko temple has six towers displayed on a platform and well-preserved carvings whereas Bakong represents the first application of the temple-mountain architectural formula on a grand scale maybe to be a suitable place to house a royal Shiva-linga in 881 A.D. Lolei, consisting of four brick towers on a double laterite platform, was an island-temple built in the middle of a now dry baray, Indratataka, the first large-scale reservoir constructed in the ancient Cambodia.
After your visit of Roluos, you can go to Phnom Bakheng, a 10th-century temple built on the top of a mountain where the Shiva-linga cult took place. The central tower of Phnom Bakheng was surrounded by 108 towers, a highly symbolic number in Hindu mythology.
Finally, you can finish by the visit of Phnom Krom, also built on the top of a mountain. Three sanctuaries housed the deities of the trinity: Shiva in the central, Brahma to the South and Vishnu to the north.
