Koh Ker was built by king Jayavarman IV in order to dedicate to Hinduism .It is located in Preah Vihear Province. There is beautiful natural attraction on the way to the temple. It is one of the oldest sites from the Khmer empire. Koh Ker was once a capital city in the 10th century. Its pyramid shape with seven tier is called as “Seven Levels of Heaven”.
The climb to the top looks daunting at times, with a wooden staircase along the one side of the temple, but do not fear. Going up the 160 steps is worth it when you see the view from the top. When you come up to the top of the castle and see the beautiful scenery, and that suits the cost came up to take the apparitions so cool.
