The crypt (_plate thirty-two_) occupies the space under the choir. The Abbé De la Rue, who terms it "_une jolie chapelle_," says that, in the fifteenth century, it was denominated the subterranean chapel of St. Nicholas; but previously to the revolution, had assumed the name of the chapel of the Holy Trinity. It was originally entered by two narrow staircases from the transepts. Its length from east to west is about thirty feet: its width, about twenty-seven. The simple vaulted roof is supported by thirty-two slender columns, sixteen of them half imbedded in the wall, and rising from a stone bench, with which this crypt is surrounded, in the same manner as that of the church of St. Gervais, at Rouen. This chapel was, till lately, paved with highly-polished vitrified bricks, each about two inches square, diversified with very vivid colors, but of a description altogether unlike those in the Conqueror's palace. It is lighted by narrow windows, which widen considerably inwards, the wall being here of great thickness; and, according to all probability, there were originally eleven of them, though the greater part are now closed. One of them was lately filled with bones, and bricked up. Upon the place it occupied is to be seen the following inscription, placed between a couple of vases of antique form:--"_Ossemens trouvés dans l'ancien chapitre des dames de la Trinité, et déposés dans ce lieu le IV. Mars, MDCCCXVIII._" [Illustration: Plate 33. ABBEY CHURCH OF THE HOLY TRINITY AT CAEN. _Capitals in the Choir._]
