Le PRASAT KOH KER (groupe de temples) se trouve également dans la province de Preah Vihear. Ce temple ressemble à une pyramide à sept niveaux. Ne manquez pas la vue panoramique depuis son sommet, idéale pour prendre des photos. Nous verrons également des temples plus petits dans le groupe : Prasat Krachap, Prasat Neang Kmao, Prasat Ling, Moat, Prasat Bram et Prasat Chen. La plupart de ces temples sont recouverts par la jungle, car cette zone a été abandonnée et récemment découverte.

Le complexe archéologique de Preah Khan de Kampong Svay, ou Prasat Bakan ou Bakan Svay Rolay, est situé à 100 km à l'est d'Angkor, dans la province de Preah Vihear, au Cambodge. Il s'agit du plus grand complexe religieux jamais construit à l'époque angkorienne, avec une superficie de plus de 22 km², même si son isolement en fait l'un des moins visités. Preah Khan de Kompong Svay abrite également un ensemble de temples et la plus grande statue de Bouddha debout.

Prasat Pram is a temple complex in Koh Ker, Cambodia, known for its five brick and laterite towers and the dramatic tree roots that have engulfed two of the structures. The name "Pram" means "five," referring to the five temples on a common terrace. It is a popular photography spot due to the striking visual of roots intertwined with ancient architecture, particularly the northeastern tower.

Prasat Neang Khmau (also known as "Lady in Black" temple) is an ancient Khmer temple complex located in either Takeo province or Preah Vihear province (Koh Ker). The name refers to the dark color of its weathered stones, which may be due to oxidation or historical fire damage. The Takeo version consists of two deteriorated brick towers from the 10th century, dedicated to the god Shiva.

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.

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 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.
