These additions, superimposed ornamentations, and rebuildings, together with the very substantial substructure of the primitive Cathedral, form to-day a small church of unimpressive, conglomerate style, and except for its history, unnoteworthy. It is therefore a church whose interest is almost wholly of the past; and the traveller goes back in imagination, century after century, to the era of Papal residency, when the Cathedral was not only ecclesiastically important, but architecturally in its best and purest form. This church, which Clement V found on his removal to Avignon, and which may still be easily traced, was of the simple, primitive Provençal style. No dates of that period are sufficiently accurate to rely upon; but its interest lies not so much in chronology as in its portrayal of the general type. The interior is the usual little hall church of the XI century, with its aisle-less nave of five bays, and plain piers supporting a tunnelled roof, with double vault arches. Beyond the last bay, over the choir, is the Cathedral's octagonal dome, and from the rounded windows of its lantern comes much of the light of the interior, which is sombre and without other windows of importance.
The façade is architecturally one of the most significant parts of the church. Above the portal the wall is supported on either side by plain heavy buttresses, and directly continued by the solid bulk of the tower. In 1431 this tower replaced the original one which fell in the earthquake of 1405. It is conjecturally similar, a heavy rectangle which quite overweighs the church; plain, with its stiff pilasters and two stories of rounded windows; without grace or proper proportion, but pleasing by the unblemished severity of its lines. Above the balustrade with which the tower may be properly said to terminate, the religious art of the XIX century has erected as its contribution to the Cathedral a series of steps, an octagon, and a colossal, mal-proportioned statue of the Virgin. These additions are inharmonious; and the finest part of the façade is the porch, so classic in detail that it was formerly supposed to be Roman, a work of the Emperor Constantine. Like the rest of the church, its general structure is plain and somewhat severe, with small, richly carved details, in this instance closely Corinthian. The rounded portal of entrance is an entablature, enclosed as it were by two supporting columns; and above, in the pointed pediment, is a circular opening curiously foreshadowing that magnificent development of the North--the rose-window. Passing through the vestibule, whose tunnel-vault supports the tower, the minor portal appears, almost a replica of the outer door, and the whole forms an unusual mode of entrance, graceful in detail, ponderous in general effect. Far behind the tower of the façade rises the last significant feature of the exterior, the little lantern. It is an octagon with Doric and Corinthian motifs, continuing the essential characteristics of the interior, and exceedingly typical of Provence.
