In 1217 Bishop Hamlin obtained the consent of Philippe-Auguste to destroy the Gallo-Roman city walls in order to extend the apse of his church, and the next year the choir was started. The bishop, trowel in hand, spent hours on the new work. His two successors continued the enterprise. From 1234 to 1255 Bishop Geoffrey de London was its princely benefactor. In 1254 the choir was dedicated, "a day of benediction" for our land, said the people with tears of fervor. Men and women worked voluntarily to clear the edifice of builders' rubbish, even the little children of four carrying out the sand in their frocks. For the happy ceremony, each guild of the city, chanting psalms, brought a candle of two-hundred-pound weight, to be set up in a majestic circle round the high altar.
The choir, then blessed for God's service, is one of the vast designs of Gothic architecture. "Words are powerless to paint the majesty of this sanctuary," wrote M. Gonse. Here, as at Bourges, is the note of dream beauty that haunts the memory, the something mysterious and superlatively picturesque. Were the church completed on the same scale it would rank with the supreme cathedrals of France. From the exterior the contrast between the XII-century nave and its towering neighbor is painfully abrupt. The nave's outer walls are stark and unadorned, the round arched windows insignificant in size. But who would be willing to forfeit the venerable monument built by the poet-theologians, Hildebert de Lavardin and Guillaume de Passavant, wherein history has been lived, and whose interior aspect is of so grave, white, and primeval a simplicity?
Overawing in size is Le Mans' Gothic choir. The ground falls away to the cast of the church, and then opens out in the Place des Jacobins, whence can be obtained an unobstructed view of the stupendous edifice. Its numerous apse chapels are of exceptional length. The forked flying buttresses allowed the insertion of ambulatory windows. As at Bourges and Coutances, the inner aisle is sufficiently high to possess its own triforium and clearstory, but Le Mans improved on Bourges by omitting altogether the triforium of its middle choir in order not to dwarf its clearstory.
