Continuing along the line of Louis XIV’s Boulevards, we reach next the Bd. des Italiens, and then turn obtusely round into the Bd. Montmartre. To our L lies the Faubourg of that name, long since swallowed up by the engulfing city. At the Rue St. Denis (the great north road of Paris), we arrive at one of the debased classical =triumphal arches= (Porte St. Denis) which Louis XIV erected in place of the ancient castellated gates. It is (more or less) decorated with contemporary reliefs representing his victories; these, and the inscriptions, are worth examining. Beyond the gate, the road to St. Denis, much traversed in earlier times by pilgrims, takes the significant name of Rue du Faubourg St. Denis. A little further on, the modern trunk line of the (Haussmannesque) Bd. de Sébastopol, hewn straight through the heart of the earlier town, intersects the old fortifications, leading R to the Cité, and L to the Gare de l’Est, in which direction it is known as the Bd. de Strasbourg. The next corner, the Rue St. Martin, which similarly changes its name to that of its Faubourg as it crosses the limit of the earlier town, is marked by a second of Louis XIV’s arches, the =Porte St. Martin= (not _quite_ so ugly), whose sculpture is again worthy of notice on historical grounds, if not on artistic. [A little way down the Rue St. Martin to the R lies the =Conservatoire des Arts et Métiers= (uninteresting internally) which occupies the site of the former =Cluniac Priory= of St. Martin-des-Champs, after which the street is still called. This was one of the principal old monasteries in the belt outside the girdling walls of Philippe Auguste, though included within those of Étienne Marcel. It was founded as early as the 11th century. The Conservatoire itself, as an industrial exhibition, is hardly worth a visit (except for technical purposes), but it ought to be inspected for the sake of the old =church= of the monastery which it contains (enter it to view interior; open on Sundays, Tuesdays, and Thursdays only) as well as for the fine =Refectory= of the 13th century, a beautiful Gothic hall, probably erected by Pierre de Montereau, the architect of the Sainte Chapelle, who also built the other Refectory, now destroyed, at St. Germain-des-Prés in the southern Faubourg. A little further on in the same street is the interesting Gothic church of =St. Nicolas-des-Champs=, with rather picturesque Renaissance additions. It stood, when first built, far out in the country. The fine west porch is of the 15th century. These buildings are chiefly worth notice as enabling the visitor mentally to restore the outer ring of monasteries and churches during the early mediæval period, afterwards englobed in the town of Louis XIV, and now in many cases adapted to alien modern uses.]
