The passage, No. 20, which is 12·25 metres long by 2·80 metres wide, communicates by a door at its northern end with the small unlighted room, No. 21. The construction here is of interest (Plate 17, Fig. 2). The passage is finished by a shallow pointed calotte, standing out from the face of the wall and spanning the angles in the usual fashion with a horizontal masonry bracket. Below it, but not in the centre of the passage, is the small doorway, which is covered by a masonry lintel. The passage opens on to court A through an arcade of two pointed arches. The arches spring from engaged columns and from a squat masonry column placed between them. The rough capital and engaged capitals, from which the stucco has disappeared, are constructed in the same way as the engaged capitals in the great hall. On the opposite side of the court there was once a similar arcade of two arches which has now fallen; indeed, the arcade of No. 20 is the only free-standing arcade which remains intact in the whole palace, with the exception of those in rooms 33 and 40. Court A, 10·70 metres by 6·25 metres, communicates with corridor 6 by a vaulted passage, 1·90 metres wide and 4·25 metres high, leading to an arched doorway 1·60 metres wide and 2·55 metres high. East of this passage lies a vaulted room, No. 26, the door of which stands in the ruined cloister, No. 25. Room 26 is lighted by two small windows in the south wall, opening on to the court, and by a window-slit in the east wall, opening on to the palace yard. To the south of court A lie three chambers, Nos. 22, 23, and 24, which have a width varying from 4·05 metres to 3·85 metres and a length of 5 metres. They communicate with each other and with the court, added to which No. 22 possesses a third door leading into No. 20, and No. 24 a third door leading into No. 25. For the door leading from No. 24 into court A space has been provided by removing a section of the dividing wall between Nos. 23 and 24.
