The first tower, hardly detached from the Tour d’Argent, is the Tour de Montgomery; the third, and smallest, but the best preserved of the three, for it still has its battlements, is the Tour Bonbec. The Sainte-Chapelle and its four towers--counting the clock tower as one--clearly define the precincts; or, as a surveyor would say, the perimeter of the Palace, as it was from the time of the Merovingians till the accession of the first race of Valois; but to us, as a result of certain alterations, this Palace is more especially representative of the period of Saint-Louis. Charles V. was the first to give the Palace up to the Parlement, then a new institution, and went to reside in the famous Hotel Saint-Pol, under the protection of the Bastille. The Palais des Tournelles was subsequently erected backing on to the Hotel Saint-Pol. Thus, under the later Valois, the kings came back from the Bastille to the Louvre, which had been their first stronghold. The original residence of the French kings, the Palace of Saint-Louis, which has preserved the designation of Le Palais, to indicate the Palace of palaces, is entirely buried under the Palais de Justice; it forms the cellars, for it was built, like the Cathedral, in the Seine, and with such care that the highest floods in the river scarcely cover the lowest steps. The Quai de l’Horloge covers, twenty feet below the surface, its foundations of a thousand years old. Carriages run on the level of the capitals of the solid columns under these towers, and formerly their appearance must have harmonized with the elegance of the Palace, and have had a picturesque effect over the water, since to this day those towers vie in height with the loftiest buildings in Paris. As we look down on this vast capital from the lantern of the Pantheon, the Palace with the Sainte-Chapelle is still the most monumental of many monumental buildings. The home of our kings, over which you tread as you pace the immense hall known as the _Salle des Pas-Perdus_, was a miracle of architecture; and it is so still to the intelligent eye of the poet who happens to study it when inspecting the Conciergerie. Alas! for the Conciergerie has invaded the home of kings. One’s heart bleeds to see the way in which cells, cupboards, corridors, warders’ rooms, and halls devoid of light or air, have been hewn out of that beautiful structure in which Byzantine, Gothic, and Romanesque--the three phases of ancient art--were harmonized in one building by the architecture of the twelfth century. This palace is a monumental history of France in the earliest times, just as Blois is that of a later period. As at Blois you may admire in a single courtyard the chateau of the Counts of Blois, that of Louis XII., that of Francis I., that of Gaston; so at the Conciergerie you will find within the same precincts the stamp of the early races, and, in the Sainte-Chapelle, the architecture of Saint-Louis.
