[Footnote 9: The room marked 48 in the plan is visible in Pl. XIII. Almost in the center of the plate, but a little to the right, two small loopholes may be seen, and to their right a doorway, all of which belong to room 48; the walls of 49 and 50 are much lower than those of 48. Behind 48 the high walls of 43 may be distinguished.] The "street" leads to an open space. Here lie three estufas (54, 55, 56), partly sunk in the ground. Much lower down is situated another estufa (57) of the same type as 44. It is surrounded by high walls.[10] South of the open space lie a few large rooms (58-61). A tower (63 in the plan; the large tower to the right in Pl. XIII) is situated still farther south, beside a steep ledge. This ledge, north of the tower (to the left in the plate), once formed a free terrace (62), bounded on the outside by a low wall along the margin. South of the tower is an estufa (76) surrounded by an open space, southeast of which are a number of rooms (80-87). In most of them, even in the outermost ones, the walls are in an excellent state of preservation. The wall nearest to the talus slope is 6 metres high and built with great care and skill.[11] South of these rooms and close to the cliff lies a well-preserved estufa (88), and south of the latter four rooms are situated, two of them (90, 92) very small. The walls of the third (91) are very high and rise to the roof of the cave. At one corner the walls have fallen in. This room is figured in a subsequent chapter in order to show a painting found on one of its walls. Near the cliff lies the last estufa (93), in an excellent state of preservation. The rooms south of this estufa are bounded on the outer side by a high wall rising to the rock above it. An excellent defense was thus provided against attack in this quarter. [Footnote 10: They are shown in the plate just to the left of the fold at its middle, rather low down.] [Footnote 11: A part of this wall may be seen to the extreme right of Pl. XIII, and also in Fig. 34 behind and to the right of the tower.] [Illustration: PLATE 5 PHOTOGRAPHED BY F. K. VREELAND THE ROUND TOWER, FROM THE NORTH GENERAL VIEW OF THE RUIN, BEFORE REPAIRING]
