The church comprises a nave and side aisles, and is substantially in the Romanesque style, but with many alterations. There are three arcades resting on piers with engaged columns in granite, with capitals carved to represent fruit, acanthus leaves, and the seven deadly sins. A pretty flamboyant doorway replaces the western porch, which had been destroyed. Over it is a window in the same style. On the right of the entrance a doorway, that seems to give access only to a passage, communicates with a chapel below the soil, dimly lighted, and containing an image of N. D. de tout Pouvoir, supposed to have been given by Agelmodis, the widow of the founder of church and monastery. It was accorded a crown in 1900 by the Pope, and the anniversary of this ceremony, July 29th, is kept as a fête at Langogne. But the great festival in the town is on the Sunday following June 19th, when is the _vogue_, in honour of the two patrons, Gervasius and Protasius. On that occasion cars are drawn through the streets bearing groups of allegorical figures; but the special sport of the day is the "chute d'eau." A species of gallows is erected in the main street, with a vessel full of water balanced in the middle. The young men vie with one another as to who by throwing a stick can upset the vessel, and then dash under it so speedily as not to be splashed by the falling water. He who succeeds receives a prize. Langogne is becoming annually more and more a summer resort. The Languiron here flows into the Allier; it does not fill its bed, which is the receptacle for the refuse from the abattoir and the town, and the odours arising from these dejections infect the otherwise pure mountain air.
