 The four cherubs who flutter against the first piers of the nave, carrying between them two holy water basins, appear of quite normal cherubic size, until approached.Then it becomes apparent that each one is over 2 metres high and that real children cannot reach the basins unless they scramble up the marble draperies.The aisles each have two smaller chapels and a larger rectangular chapel, the Chapel of the Sacrament and the Choir Chapel.
