In our day the Conciergerie, hardly large enough for the prisoners committed for trial--room being needed for about three hundred, men and women--no longer receives either suspected or remanded criminals excepting in rare cases, as, for instance, in these of Jacques Collin and Lucien. All who are imprisoned there are committed for trial before the Bench. As an exception criminals of the higher ranks are allowed to sojourn there, since, being already disgraced by a sentence in open court, their punishment would be too severe if they served their term of imprisonment at Melun or at Poissy. Ouvrard preferred to be imprisoned at the Conciergerie rather than at Sainte-Pelagie. At this moment of writing Lehon the notary and the Prince de Bergues are serving their time there by an exercise of leniency which, though arbitrary, is humane. As a rule, suspected criminals, whether they are to be subjected to a preliminary examination--to “go up,” in the slang of the Courts--or to appear before the magistrate of the lower Court, are transferred in prison vans direct to the “mousetraps.” The “mousetraps,” opposite the gate, consist of a certain number of old cells constructed in the old kitchens of Saint-Louis’ building, whither prisoners not yet fully committed are brought to await the hour when the Court sits, or the arrival of the examining judge. The “mousetraps” end on the north at the quay, on the east at the headquarters of the Municipal Guard, on the west at the courtyard of the Conciergerie, and on the south they adjoin a large vaulted hall, formerly, no doubt, the banqueting-room, but at present disused. Above the “mousetraps” is an inner guardroom with a window commanding the court of the Conciergerie; this is used by the gendarmerie of the department, and the stairs lead up to it. When the hour of trial strikes the sheriffs call the roll of the prisoners, the gendarmes go down, one for each prisoner, and each gendarme takes a criminal by the arm; and thus, in couples, they mount the stairs, cross the guardroom, and are led along the passages to a room contiguous to the hall where sits the famous sixth chamber of the law (whose functions are those of an English county court). The same road is trodden by the prisoners committed for trial on their way to and from the Conciergerie and the Assize Court. In the _Salle des Pas-Perdus_, between the door into the first court of the inferior class and the steps leading to the sixth, the visitor must observe the first time he goes there a doorway without a door or any architectural adornment, a square hole of the meanest type. Through this the judges and barristers find their way into the passages, into the guardhouse, down into the prison cells, and to the entrance to the Conciergerie.
