An interior tower, rather more than twenty feet square, runs up the whole height of the Moorish portion of the building; between which and the external walls an easy ascent is contrived on an inclined plane. The necessity of introducing light throughout the ascent accounts for the different elevation of the windows and ornaments of the different sides; but the architect has so managed this difficulty, that no bad effect is produced in the external view. At the lower part of the tower the ascent is sufficiently wide to admit of the passage of two men on horseback abreast; but it becomes narrower as it approaches the summit. Queen Christina is said to have been drawn up in a small carriage. The walls, both of the inner and outer tower, increase in thickness as they rise, and as the ascending plane decreases in width: a plan which appears opposed to the principle usually adopted by modern architects. It is known that Geber was the architect of the Giralda, but no certainty exists respecting its date. The Spanish antiquarian Don Rodrigo Caro supposes it to have been erected during the reign of Benabet Almucamus, King of Seville, shortly before the appearance in Spain of the Almoravides; but this is no more than a conjecture, founded on the supposed wealth of that King, who possessed larger states than his successors, and who paid no tribute to the sovereigns of Castile. Immediately over the highest story of the Moorish tower is the belfry. The bells are suspended on the centre of revolving beams, which traverse the open arches of the four faces of the tower. They are consequently in full view, as they throw their somersets and send forth their lively clatter on a _dia de fiesta_. Their effect is very original, and as unlike as possible to the monotonous and melancholy cadence of an English peal. None of them are deep-toned nor solemn, but all high and sharp: so that being let loose in merry disorder, and without tune, they somehow appear to harmonize with the brilliant skies, just as the descending ding-dong in England suits the gloom of the northern heavens. Leave Seville, and never shall their tones steal on your memory without your being transported into a blaze of bright sunshine.
