direct communication between court V and the palace. The gateway was an important structure. From the western court (U) a porch 2·70 metres deep opened through an archway 3·70 metres wide into a rectangular vaulted chamber (83) 4·50 metres from east to west (Plate 60, Fig. 2). To the east of 83 lay a chamber (82) almost square (5·90 × 5·80 metres) having a rectangular vaulted niche, 1·50 metres deep, to north and south and an archway to the east opening into court V. No. 82 must have been covered by a dome, which was in all probability set over the angles on squinch arches (see below, Plate 69), but no part of the dome is standing (Plate 61). On either side of the gateway there are four chambers accessible only from court V. No. 85 opens into the passage, probably vaulted, which was formed by the northern arcade; No. 89 opens on to the area outside the southern arcade. It would be natural to expect that an outer wall ran parallel to this arcade, dividing court V from the park, and I looked for traces of such a wall, but did not find them. Court V (18·50 × 102·50 metres) terminates in a group of much-ruined buildings of which I could only make out the general plan. The arcaded passage (92) ends in a small vaulted and unlighted room (93) (6·55 × 3·55 metres). To the south of 93 are two large chambers (94 and 95), No. 94 terminating at the southern end in a deep niche. Nos. 93 and 94 are separated by a narrow passage from a small rectangular court (W) having two chambers at either end. Of these chambers Nos. 99 and 100 are completely ruined, but the vaults of Nos. 97 and 98, which are built partly under the upper platform, are standing (Plate 62). To the south lies another small court (X) out of which the passage 101 leads into a small rectangular chamber (102) which in turn communicates with the arcaded corridor 103. This corridor runs round the eastern end of the platform which is carried over it on a vault. The vault, which was very roughly constructed, is noticeably pointed, especially on the east side (Plate 51, Fig. 1). Three double ramps provided access to the platform, the eastern pair being the largest and most important. The eastern ramps begin opposite the fourth detached pier at either end of the arcade of the corridor, where a mass of masonry 6·60 metres long by 4·90 wide blocks the adjoining arch. Vaults carrying the ramp are placed before the seventh and eighth arches from either end of the arcade, and in front of the central arch lies a vaulted chamber 3·75 metres wide. The length of this double ramp is 48 metres (Plate 63, Fig. 1). On the west side of the corridor there are nine vaulted chambers, 5·80 metres deep, which are tunnelled out under the platform. Their doorways correspond with the arches of the corridor. A detached chamber lies at either end of the corridor. The north and south ramps are constructed in the same fashion, but they are only 30·80 metres long. Opposite the central vault there is
