Roluos Rroup

The Roluos Group consists of four monuments from the Angkor era, situated not within the primary Angkor Park but in proximity to the small town of Roluos, approximately 12 kilometers east of Siem Reap. These monuments are known as Bakong, Preah Ko, Lolei, and Prei Monti.
These four temples hold historical significance as they represent the remnants of Hariharalaya, the second capital of the Khmer Empire during the Angkor period. Constructed under the reign of King Jayavarman II, the capital was relocated to Roluos from Mahendraparvata. The latter, which had a population comparable to that of contemporary Phnom Penh, served as the original capital of Angkor and was situated on the slopes of Phnom Kulen, a mountainous plateau rich in historical context.
The final monarch to reside in Hariharalaya was Yasovarman I, who, in 905 CE, commissioned the first significant temple structure at Angkor, known as Phnom Bakheng, and subsequently established the capital there.

Roluos Group Temples
The Roluos group of temples is distinguished by its unique and captivating features:
- Bakong Temple
Regarded as the centerpiece of the Roluos Group, Bakong is the first temple mountain of its kind, comprising five tiers and a central tower that reaches an impressive height of 15 meters. It served as the state temple in the heart of Hariharalaya. Although it experienced a collapse at one point, restoration efforts were undertaken by the French between 1937 and 1945. Additionally, the site includes the striking Bakong Pagoda, which is contemporary in design and adorned with intriguing murals. The pagoda remains in excellent condition and continues to be actively utilized. - Preah Ko
Surrounded by statues of bulls, the name of this temple translates to “sacred bull.” It boasts exquisitely preserved carvings and consists of six towers, each housing a small, active shrine. - Lolei
This temple is distinctive as it is situated on an island, encircled by a man-made reservoir known as baray in Khmer. However, the reservoir has since dried up. The temple comprises four dilapidated towers and represents the final construction by Yasovarman I before relocating the capital to the Angkor region. - Prei Monti
Regarded as the most secluded and least frequented temple within the Roluos group, Prei Monti is a diminutive temple ruin hidden from the main thoroughfare and obscured by the surrounding village. Although it now consists of a mere cluster of one-story ruins overtaken by jungle, its hidden charm and obscurity render it a worthwhile destination.
How To Get There
Roluos Group is situated just 12 kilometers to the east of Siem Reap, conveniently located off National Road 6. This route leads towards Phnom Penh, which typically results in significant traffic congestion. The road is well-paved and suitable for cycling; however, due to the heavy traffic, it is advisable to arrange for a tuk-tuk for your journey to and from the site. This service can be organized through your hotel staff or directly with the numerous tuk-tuk drivers who are readily available throughout Siem Reap.
While the Roluos Group is not part of the Angkor Archaeological Park, a temple pass is necessary to access these historical sites. It is important to purchase this pass in advance from the official ticket office located on Road 60, near the park’s entrance, as temple passes are not available for purchase at Roluos.
Best Time to Visit
A half-day tour from Siem Reap allows for a visit to the Roluos group. It is advisable to schedule your trip in the morning, starting with a stop at Phsar Leu Market. This market, situated en route to the temples, offers an authentic experience and is frequented by many locals, making it the largest market in Siem Reap. English is not commonly spoken here, providing an opportunity to engage with the vibrant displays of fresh meat, fruits, vegetables, and a diverse array of household goods.
We recommend an itinerary that combines a visit to Phsar Leu Market and the Roluos Group in the morning, followed by a trip to Wat Athvea at Phnom Krom in the afternoon. Phnom Krom is also a splendid spot for sunset viewing.
