Just outside this gate is the Pilar de Carlos V., a fountain in the Greco-Roman style, erected by the Alcaide Mendoza in 1545. It is ornamented with the Imperial arms, and sculptured heads of the river gods, Genil, Darro, and Beiro. The double Torre de los Siete Suelos flanks a gateway, now walled up, which was formerly the principal entrance to the fortress. Through it the unfortunate Boabdil is said to have passed on his way to exile and obscurity. The tower is so called because it is believed to descend seven storeys underground. Four subterranean chambers have been investigated. Here tradition places the site of much buried treasure, and fables are told of phantom guards and enchanted sentries. At the south-eastern angle of the _enceinte_ is the ruinous Torre del Agua, which derives its name from the aqueduct that at this point spans the ravine. On the north-eastern side we reach the Torre de las Infantas, the interior of which is a perfect model of the smaller Oriental dwelling-house. Through a small vestibule we reach a covered-in patio with a fountain in the centre, and alcoves opening out on three sides. The ornamentation is graceful and original. The tower is one of the most interesting parts of the fortress. Somewhat less complete and regular in its plan, but even more elegantly decorated with rose-coloured tiles, is the adjoining Torre de la Cautiva (Captive’s Tower). Here the inscriptions resound the praises of Abu-l-Hejaj and refer to the _Lion_ residing within these walls--a very different occupant from a captive! The Torre de los Picos seems to have been so styled from the peaked battlements which crown it. It evidently underwent extensive remodelling about the time of the Spanish Reconquest, but some relics of the Nasrite rule remain in the shape of some beautifully moulded twin windows. The Torre de Ismaïl, or de las Damas (Ladies’ Tower), was given by Mohammed V. to his son Ismaïl, and has a richly decorated belvedere and a hall very tastefully ornamented. The ruined tower of Puñales has some curious stucco decorations, differing from those found in other parts of the palace. Between the Torres de los Picos and de las Damas is a little _mihrab_ or oratory built on the wall. At the Reconquest it was appropriated to the private use of one Astasio de Bracamonte. Though it has undergone deplorable “restorations,” the _kiblah_ or easterly niche and other indications of the Muslim rite can still be made out. Strangely enough, the portal is guarded by two Moorish lions brought from the old Mint--the injunctions of the Mohammedan religion being thus ignored in its own temple!
