The houses were built of brick with limestone quoins supported on arcaded stone ground floors and capped by steep slate roofs with dormers, very like the contemporaneous façades of Place des Vosges. There were originally two entrances to the Place Dauphine, one at the "downstream" point, through a kind of gateway centred on paired pavilions facing the equestrian statue of Henry IV on the far side of the Pont Neuf, and the second in the centre of the eastern range. Badly damaged during the turmoil of the Paris Commune of 1871, the eastern range was swept away in 1872 to open the view to the monumental white marble Second Empire "Palais de Justice" (built 1857–68), like a glazed colonnade centred on the Place Dauphine, the remains of which now form a kind of forecourt to it. Few visitors penetrate the Place Dauphine, which lies behind them, and where all the other buildings have been raised in height, given new façades, rebuilt or replaced with heightened pastiches of the originals. Three medieval buildings remain on the Île de la Cité (east to west):  The oldest remaining residential quarter is the Ancien Cloître. Baron Haussmann demolished some of the network of narrow streets, but was dismissed in 1869 before the entire quarter was lost. Old engraved maps of Paris show how, when the Pont Neuf was built, it grazed the downstream tip, the "stern" of the island-ship. Since then, the natural sandbar building of a mid-river island, aided by stone-faced embankments called "quais", has extended the island, which is planted as the small Vert Galant park ("square du Vert-Galant"), named for Henry IV of France, the "Green Gallant" king whose statue stands near the center of the bridge. It retains the original low-lying riverside level of the island. Nearby, a discreet plaque ("removed prior to 01/06/2017 and replaced with a printed sign)" commemorates the spot where Jacques de Molay, Grand Master of the Knights Templar, was burnt at the stake, 18 March 1314. The upstream tip of the island is the site of the "Mémorial des Martyrs de la Déportation," a memorial to the 200,000 French citizens who were deported to German labour camps during the Second World War.
