In addition to being the governor of the royal dwelling this concierge was the guardian of the royal prisoners. In 1348 he was further invested with the official title of Bailli and the post was, at times, occupied by the highest and the most noble in the land, among others Philippe de Savoie, the friend of Charles VI, and Juvenal des Oursins, the historian of this prince. The first to combine the two functions, that of Bailli and Concierge, was Jacques Coictier, the doctor of Louis XI. As a virtual prison the Conciergerie only came to be transformed when Charles V quitted the residence of the Palais de la Cite, and the Conciergerie, as such, only figures on the Tournelles registers under date of 1391. The fire of the latter part of the eighteenth century destroyed a large part of the building, but enough remained to patch together the most serviceable of Revolutionary prisons, for at one time it held at least twelve hundred poor souls, of whom two hundred and eighty-eight were killed off at one fell blow. But one woman among them all actually came to her death within the prison walls. This was La Belle Bouquetiere of the Palais Royal who, in an access of jealous furor, horribly mutilated a royal guardsman, and for this met a most cruel death by being transfixed to a post and submitting to a trial of "_le fer et le feu_." In just what manner the punishment was applied one can best imagine for himself. The Revolutionary role of the Conciergerie is a thing apart from the purport of this book, hence is not further referred to. Going back to the time of Francis I, among the famous prisoners of state were Louis de Berquin, the Comte de Mongomere, the regicides Ravaillac and Damiens, the Marechal d'Ancre, Cartouche, Mandrin and others. To-day, as a prison, the Conciergerie still performs its functions acceptably, safeguarding those up for the assizes, and those condemned to death before being sent on their long journey. The three great flanking towers of the Conciergerie are its chief architectural distinction to-day. That of the left, the largest, is the Tour d'Argent, that of the middle, the Tour Bonchet, and the third, the Tour de Cesar or the Tour de l'Horloge. This last is the only one which has preserved its mediaeval crenulated battlements aloft. The great clock has been commonly considered the largest timepiece of its kind extant, but it is doubtful if this now holds good with railways and insurance companies vying with each other to furnish the hour so legibly that he who runs may read. Across the Pont au Change, from the Palais de la Cite, by the Louvre and out into the Faubourg Saint Antoine, one comes to the Place des Vosges, the old Place Royale, which occupies almost the same area as was covered by the courtyard of the Palais des Tournelles, so called from its many towers.
