This western façade is actually the frontispiece of a vast porch or narthex that stretches back through four of the bays of the nave, with flights of steps, eleven in each, and with landings between. Half-way up the porch are two chapels, one on each side, with large oak doors carved and painted. They represent groups of figures from the story of the Gospel. The background is sunk, but the surface left smooth, and is painted. The chapel on the right is dedicated to S. Stephen, that on the left to S. Giles. Neither is now used.
On two of the steps of the ascent is inscribed in Latin, "Ni caveas crimen, caveas contingere limen, Nam Regina poli vult sine sorde coli." "Unless free from guilt shun this threshold, for the Queen of Heaven will be worshipped only by a guiltless soul."
Formerly at the head of the fourth landing was a central doorway leading into the nave by another flight of steps continued inside the church; and it was said of Notre Dame du Puy, that you went in at the navel and came out at the ears, i.e. at the lateral doors in the transepts. But the central entrance has been walled up, and a floor been laid over these steps. Access is now obtained to the nave by a side flight that turns round the church and gives admission in the south transept. The corresponding lateral flight gives access to the magnificent cloister, partially closed by a gate of intricate and beautiful ironwork. The arcade in the cloister rests on twin columns with richly carved capitals, no two alike, and the wall space above the arcade is filled in with mosaic work of red, yellow, white, and black.
The interior of the church is not less remarkable than the exterior. Originally it consisted of a small square basilica, now forming the retro-choir; this was prolonged into nave with aisles, and transepts were added forming a Greek cross, with a dome at the intersection. Later on the church was carried further westward, and the singular western portion, a nave over a porch, was raised in the twelfth century.
Porch, Cathedral, Le Puy
Each bay of the nave is surmounted by an octagonal cupola. Two sides contain windows looking north and south. Two sides have also windows sustained on an arch flung across the nave, and looking into it. The four other sides of the octagons are in the depth of the wall. The lateral south porch, opening on to the little Place du For, where is the episcopal palace, is a noble piece of work. Two bold arches give access to it. To the left is a doorway only opened for a pope to pass through; the other gives admission to ordinary personages into the transept.
The tower is a campanile detached from the church, unbuttressed, and though fine, is too small for the size of the minster. But this is due to the fact that every inch of space on the rock was precious, and had to be economised. Accordingly a tower of greater bulk at base would have encroached on the way of access to the basilica. There are two more doorways, one, further on, a bold and daring sweep that spans not the entrance only, but also the little street. A third is on the north side.
Until this year, 1906, the head of the French State, King, Emperor or President was ex officio lay canon of Le Puy, just as our King is a lay canon of S. David's. But with the separation of Church and State in France, this has ceased, and M. Loubet was the last of the lay canons of Le Puy.
