As we have seen, the only one of the seven minor entrances to the cathedral is the _Puerta Santa_, or, as it is sometimes called, _la Puerta de los Perdones_; it opens upon the _Plaza de los Literarios_, to the west of the cathedral. This is the Jubilee door, and is only opened once in every seven years, on the occasions when the feast of Santiago falls upon a Sunday; the archbishop himself performs the ceremony. The Jubilee is celebrated in accordance with the privilege conceded by Calixtus II. in the year 1122. The _Puerta Santa_, of which the original sculpture has disappeared, is now adorned with twenty-four Byzantine statues, whose inscriptions have gone: there are twelve of these in twelve niches on either side, which have been utilised from the _débris_ of the older parts. Above the door is a large statue of St. James in pilgrim’s garb with staff in hand; and on either side of him, also in niches but some three sizes smaller, are the two disciples who were buried with him. On the tympanum of the inner door are inscribed the words: “_Haec est Domus Dei et porta Coeli_.” Every Jubilee year for many a century a choir of blind peasants has stood by this door and sung to those who entered the simple folk-songs of their native land. Another entrance on the same side of the cathedral, and the one by which pilgrims have been wont to enter the sacred precincts from time immemorial, is called _la Façade y Puerta del Reloj_, or the façade and door of the clock. It is also called the _Quintana_; because the square upon which it opens was once the _Quintana de los Muertos_, or the cemetery of the canons. This square is one of the finest in the town: its name was changed in honour of those brave students of the University who formed themselves into a battalion at the time of Napoleon’s invasion, and fell fighting for the deliverance of their country. A white marble tablet on the fortress-like wall of the convent of San Payo, which forms the side of the square opposite to the cathedral, bears an inscription to their memory. Another side of the square is formed by a huge monastic pile--the convent of Antealtares--and on the south the handsome granite building with Doric columns now used as post and telegraph offices. Many a time have I stood in front of the post office, sometimes to take a photo of the cathedral, and sometimes to admire the winding granite balustrades upon the battlement-like towers and cupola which rise majestically behind the western front. This façade, with its four stout Doric columns, replaced the original Romanesque entrance towards the end of the seventeenth century. The heads of many of the statues on either side of the entrance have long since disappeared.
