has now two surrounding walls inside of the moat. The first wall (inner wall) is made of brick; the second wall (outer wall) with a length of and a breath of is made of laterite. Two doors are in the east and in the west. The doors of the second wall have a cruciform plan. The doors of the first wall are smaller and not of cruciform layout. The plane between the first and second wall is completely overbuilt with rectangular structures, possibly later additions. In the center court is the sanctuary and opposite it are two socalled libraries. Behind the sanctuary on a rectangular platform stand nine towers in two rows (one of five, one four towers). Twelve smaller prasats in groups of three surround the platform. All 21 towers once housed lingas. Prang The seventiered pyramid called Prang was probably the state temple of Jayavarman IV. Construction of the sanctuary was started in 928 AD. At ground level one, side of the square building measures . The height is . Originally on the top platform stood a huge lingam probably more than high and having a weight of several tons. Inscriptions say that it was the tallest and most beautiful Shiva-ling-am. The ling-am probably stood in a shrine which some researchers say could have been about high. On the north side of the pyramid is a steep staircase leading to the top. The original stairs are in a very bad condition as is the bamboo-ladder which was constructed in the 20th century, so it is forbidden to climb to the top of the pyramid via this route. There is however a new staircase which can be used to ascend to the top tit of the pyramid. Concerning the seventh tier some scientists say, this was the platform of the shrine because on its sides beautiful reliefs of Garudas were made. There is just one Khmer temple which resembles the temple Baksei Chamkrong in Angkor. But the fourtiered monument there is much smaller and has a staircase on each of the four sides. On the platform on the top of the Baksei Chamkrong is a prasat in a good condition. Tomb of the White Elephant Behind the court with the seventiered pyramid is an artificial hill of exact circle form covered with trees. It is named Tomb of the White elephant. "The white Elephant" is a very well-known legend
