The Louvre is the noblest monument of the French Renaissance. From the time of St. Louis onward, the French kings began to live more and more in the northern suburb, the town of the merchants, which now assumed the name of La Ville, in contradistinction to the Cité and the Université. Two of their chief residences here were the Bastille and the Hôtel St. Paul, both now demolished--one, on the Place so called; the other, between the Rue St. Antoine and the Quai des Célestins. But from a very early period they also possest a château on the site of the Louvre, and known by the same name, which guarded the point where the wall of Philippe Auguste abutted on the river. François I. decided to pull down this picturesque turreted medieval castle, erected by Philippe Auguste and altered by Charles V. He began the construction in its place of a magnificent Renaissance palace, which has ever since been in course of erection. Its subsequent growth, however, is best explained opposite the building itself, where attention can be duly called to the succession of its salient features. But a visit to the exterior fabric of the Louvre should be preceded by one to St. Germain l'Auxerrois, the parish church, and practically the chapel, of the old Louvre, to which it stood in somewhat the same relation as the Ste. Chapelle to the home of St. Louis. Note, however, that the church was situated just within the ancient wall, while the château lay outside it. The visitor will doubtless be tolerably familiar by this time with some parts at least of the exterior of the Louvre; but he will do well to visit it now systematically, in the order here suggested, so as to gain a clear general idea of its history and meaning.... Begin by understanding distinctly that this court is the real and original Louvre; the rest is mere excresence, intended to unite the main building with the Tuileries, which lay some hundreds of yards to the west of it. Notice, first, that the Palace as a whole, seen from the point where you now stand, is constructed on the old principle of relatively blank external walls, like a castle, with an interior courtyard, on which all the apartments open, and almost all the decoration is lavished. Reminiscences of defense lurk about the Louvre. It can best be understood by comparison with such ornate, yet fortress-like, Italian palaces as the Strozzi at Florence. Notice the four opposite portals, facing the cardinal points, which can be readily shut by means of great doors; while the actual doorways of the various suites of apartments open only into the protected courtyard. This is the origin of the familiar French porte-cochère.
