The city of Granada[252] has twelve gates; and is about eight miles round, defended by high walls, flanked with a multitude of towers. Its situation is of a mixed kind; some parts of it being upon the mountain, and other parts in the plain. The mountainous part stands upon three small eminences; the one is called Albrezzin; which was inhabited by the Moors that were driven out of Baezza by the Christians. The second is called Alcazebe; and the third Alhambra. This last is separated from the other parts by a valley, through which the river Darro runs; and it is also fortified with strong walls, in such a manner as to command all the rest of the city. The greatest part of this fortified spot of ground is taken up with a most sumptuous palace of the Moorish kings. This palace is built with square stones of great dimensions; and is fortified with strong walls and prodigious large towers; and the whole is of such an extent as to be capable of holding a very numerous garrison. The outside has exactly the appearance of an immense romantic old castle; but it is exceedingly magnificent within. But before we enter, we must take notice of a remarkable piece of sculpture over the great gate; there is the figure of a large key of a castle-gate, and at some distance above it, there is an arm reaching towards it; and the signification of this emblematical marble basso-relief is this:--that the castles will never be taken till the arm can reach the key. Upon entering, not only the portico is of marble, but the apartments also are incrusted with marble, jasper, and porphyry, and the beams curiously carved, painted, and gilt; and the ceilings ornamented with pieces of foliage in stucco. The next place you come to is an oblong-square court, paved with marble, at each angle of which there is a fountain, and in the middle there is a very fine canal of running water. The baths and chambers, where they cooled themselves and reposed, are incrusted with alabaster and marble. There is an exceeding venerable tower, called La Toure Comazey; in which are noble saloons, and fine apartments; and all perfectly well supplied with water. In the time of the Moors, there was a kind of espalier, or cut hedge of myrtle, accompanied with a row of orange trees, which went round the canal.
