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.
