Prea sat Kéo.
Two hundred metres from the bridge rise, amidst the forest, the imposing ruins of Prea sat Kéo, to reach which you have to cross a deep moat. This done, you arrive at the exterior wall, which has four entrances formed by elegant pavilions, with staircases of eight steps leading to a terrace raised nearly 2 metres from the ground; from this you pass into a low narrow gallery with numerous interior windows ornamented with twisted bars. This gallery surrounds the building, and you ascend to it by a staircase leading to a second terrace. Three other terraces, each more than 3 metres 50 centimetres wide, rise one above another, supported on blocks of well-cut sandstone.
Each terrace forms a perfect square, the sides of the first measuring each 30 metres in length. A staircase, 15 metres high and 3½ metres wide, leads to the top; and a wide parapet to the staircase serves as a pedestal for four statues of lions, more or less injured. In the centre of the upper terrace is a lofty tower, and there are four smaller ones at the corners. Each tower has four porticoes with staircases, which rest on a base 7 metres high, and these towers are reached by staircases of twenty-two steps. From them a magnificent view is obtained over the surrounding forest. They, as well as their bases and staircases, are built of great blocks of granite arranged in regular tiers, and joined together in the most perfect manner. There is little sculpture, and the doorways have been left unfinished. The towers are without roofs, and perhaps never had any. The whole building appears very ancient, judging by the condition of the stone, which in many places is falling to pieces.
