The roof--and in this respect it resembles all the other buildings--is a double one, constructed externally of sculptured stone, the blocks in the interior being plain; they were formerly hidden by a ceiling, also sculptured, of which some remains may still be remarked. The edifice divides the wall into two equal parts; upon the other sides, and facing the monument, are three pavilions, 33 metres in length. [Illustration: Drawn by M. Guiaud, from a Sketch by M. Mouhot. TEMPLE OF ONGCOR WAT, NORTH SIDE.] This imposing colonnade, which, from its great length and beautiful proportions, attracts the attention from a distance, forms a fitting entrance to the great monument. _The Temple._--Commencing from the building which forms the principal entrance, is a second causeway, 9 metres wide by 342 metres in length; it is raised 1 metre from the level of the ground. It is covered with huge blocks of stone, carefully joined together throughout its entire length, and is surrounded by a balustrade, partially in ruins, about 10 centimetres high, composed of long stones, with bevelled edges, very massive, and covered with sculptures. On each side are six platforms of earth, ascended by several steps, upon each of which is a serpent with seven heads, some erect, others thrown back. In the centre of the causeway are two elegant pavilions, one on each side, having at each extremity a portico 33 metres 66 centimetres in length. At the end of the causeway, and at the foot of the terrace, are, on each side of the latter, two ponds or sheets of water. A balustrade, like that of the causeway, and resting like it upon a sculptured basement, springs from the foot of the terrace, and runs all round the monument. At certain intervals there are large staircases of several steps each. _The Terrace._--The terrace is 2 metres 30 centimetres in height, and is surrounded by 112 fluted columns, surmounted by capitals, formed in each case of one single block of stone. The basement, like that of the whole building, is ornamented with very beautiful sculptured cornices, varied in style, and entirely covered with delicate carvings representing roses and arabesques, worked with the chisel, with a taste and skill equally wonderful. This terrace forms a cross, each arm of which is 122 metres in length, and 12 metres 16 centimetres wide. There are three flights of steps, upon each of which are four lions reclining upon their pedestals. _The Portico._--This is 6 metres in length, and is supported by six columns, four of which are detached from the monument. The temple is formed of three distinct parts raised in the form of terraces one above the other. _The Galleries._--The galleries form a rectangle, the façade of which is 180 metres in length; the sides 216 metres 16 centimetres by 4 metres 16 centimetres.
