For two hundred years and more did the architects who followed Pedro Perez add bit by bit, leaving their mark on its stones. Partly constructed of granite it is immensely strong. A softer stone has been used with great discretion in the decorative portions of the building.
No comprehensive view of the Cathedral is obtainable, so closely do the houses surround it on the south and east, and creep up the hill on which it is built, on the north. The west front is best seen from the Plaza Ayuntamiento, a pleasant little garden which the Town Hall bounds on one side. I managed a sketch from the narrow street below this garden.
Only one of the two towers of the west façade is finished as originally intended. The other is capped by a dome, designed by El Greco, that painter of the weird, and under which is the chapel wherein the Mozárabic ritual is celebrated daily at 9 A.M.
The great west door, La Puerta del Perdon, is enriched with embossed bronze work. Flanking on it either side are the doors of Las Palmas, and de los Escribanos. The arches of all three have figures in the jambs, which are continued round each arch in the very best Gothic of the fifteenth century. Above the doors the façade is adorned with a sculptured Last Supper and colossal figures in niches. In the centre is a splendid rose window twenty-eight feet in diameter.
The north transept is entered from the steep Calle de la Chapineria by La Puerta del Reloj, the oldest doorway of the Cathedral. Its bronze doors, of later date than the doorway, were cast to match those of La Puerta de los Leones in the south transept. This doorway's name is derived from the Lions, which holding shields, occupy positions on its pillars. Another entrance is through La Puerta de la Presentacion which opens on the cloisters.
The effect produced by the magnificent interior is much enhanced by the beauty of the glass which fills most of the windows. The earliest are on the north side of the nave, and form a series which was commenced in 1418 and finished one hundred and fifty years later. The glass in the rose window over the west door is superb, and the same may be said for that in the north transept and the wheel window over La Puerta de los Leones.
There is no triforium, and the transepts do not project beyond the nave. The arches of the very beautiful chancel serve as niches for figures. Here in each bay is a rose window forming a clerestory, and the colours in the glass of these shine like jewels in a crown.
