The Prasat Phanom Rung is very popular with Thais and it can get very crowded during holidays.
The whole complex has been renovated last century and it look very well preserved. The whole thing has been converted into a National Historical Park and there is a a small admission fee to visit.
The main sanctuary has a cruciform plan, with four galleries, one on each side.
Each gallery has its own entrance and in correspondance of each entrance there is a decorated tower, very similar, but smaller, to the main huge tower overlooking the whole complex.
The Prasap Phanom Rung dates back to the 10th century, but it was completed in the 13th century. In this period this region of Thailand was part of the vast Khmer empire and the Prasat Phanom Rung has been built in classical Angkor style as a Hindu temple. Only in the 15th century, when the Thai kingdom took over this region, the whole complex has been converted into a buddhist monument. Many reminiscences and statues of the Hindu period are still present, anyway.
It is difficult to get to the Prasat Phanom Rung, but still it's possible to do the visit as a daytrip. Arriving in Nang Rong, on the major road from Khorat to Buriram, should be easy by bus. Once you're there you reach Ban Ta Ko, a few kms away, by local bus. From here you should be able to find pick up trucks going uphill to Ban Don Nong Nae and then to the Prasat Phanom Rung or you can go by "motorcycle-taxi" with some of the local guys.
There are always many buddhist monks visiting the Prasat Phanom Rung.
Most of them are curious and they like to have some contact with western tourists. They usually like to be photographed, but asking permission is always better.
The Prasap Phanom Rung is located on top of a 400 mt high hill. There are some terraces at the entrance of the complex where it's possible to enjoy some breathtaking views of the landscape around.
The border with Cambodia can be seen far away and also some of the many police checkpoint and observation points around.
Fondest memory: Walking on the long stone promenade to the stairs and then up to the entrance gate of the temple, together with all the thai pilgrims and monks, has been a fascinating experience.
