Koh Ker is a 10th-century temple complex in the north Cambodian jungle. A former capital of the Khmer Empire, the site is now remote and heavily forested. The main structure, Koh Ker Temple, is a stepped 7-tiered pyramid. The large rectangular tank, Rahal Baray, supplied water to the complex. The Prasat Krahom, meaning "red temple," is known for its sandstone carvings, while Prasat Pram is covered in strangler figs. You'll see more temples as tripadvisor not catching temples location.

The most south sanctuary of this group is the Prasat Pram on the west side of the road. A small (300 metres (328 yd) long path leads to the monument. It has five towers or prasats (pram = five). Three brick towers stand in a row on the same platform. They face east. The central one is a bit taller than the others. In each of these prasats, once stood a lingam. These and the beautifully carved lintels were looted. Two prasats (faced west) are standing in front of the platform. One is built of brick and has diamond‑shaped holes in the upper part. This fact indicates that this tower once served as a fire sanctuary (fire cults were very important during the era of the Khmer kings).

Prasat Neang Khmao ist ein großer quadratischer Tempel aus Laterit auf einem Sandsteinsockel, der von einer Lateritmauer umgeben ist. Er besteht aus mehreren Zwischenebenen, die sich nach oben hin verjüngen und Akzentstücke aufweisen. An jeder Ecke befindet sich ein dekoratives „Mini-Prasat“-Stück. Im Sandsteinsockel sind noch Spuren wunderschöner dekorativer Schnitzereien erhalten. Es ist einer der am besten erhaltenen Tempel überhaupt.

Prasat Banteay Pichean is a rarely visited ancient temple located within the Koh Ker temple complex in the Preah Vihear Province of Cambodia. It dates to the 10th century, during the reign of King Jayavarman IV.

Prasat Chrap is a 10th-century Khmer temple complex in Koh Ker, Cambodia, characterized by three large, partially ruined laterite towers standing in a row within a laterite enclosure wall. It also features two smaller brick structures, possibly libraries or earlier shrines, located opposite the main towers.

Prasat Linga is a temple housing a massive linga, a symbolic pillar representing the Hindu god Shiva. These temples, often found at sites like Koh Ker, feature a large, monolithic stone linga (often 2 meters high) on a yoni pedestal (the female symbol). Many of these temples, likely unfinished or missing perishable roofs, were designed so that rainwater could flow over the linga, pooling in a ceremonial tank below.
