To the north side of Les Halles, we find Rue Mondétour, dating from 1292, but many of its ancient houses have been razed; modern ones occupy their site. A dancing-hall in this old street was the meeting-place of French Protestants before the passing of the Edict of Nantes. No. 14 has cellars in two stories. The church St-Eustache is often familiarly referred to by the market women as Notre-Dame des Halles. The crypt, once the chapel Ste-Agnes, the nucleus of the grand old church, dating from 1200, secularized but still forming one with the sacred building, is a fruiterer’s shop--truly St-Eustache is the church of the Markets. The edifice as it stands dates as a whole from the seventeenth century. Gothic in its grand lines, very strikingly impressive, it has a Jesuit frontage, substituted for the Gothic façade originally planned, and Renaissance ornamentation within. The church was mercilessly truncated in the eighteenth century to allow for the making and widening of surrounding streets. Rue du Jour under other names has existed from the early years of the thirteenth century, but was then close up against the city wall of Philippe-Auguste. Nos. 3, 4, 5, 7, 11 are ancient, and No. 25, with its traces of bygone ages, is believed to be on the site of the house where Charles V made from time to time a _séjour_, hence the name, truncated, of the street. Rue Vauvilliers, until 1864 Rue du Four St-Honoré, dates from the thirteenth century. Here, at No. 33, lodged young Buonaparte, the future Emperor, at the ancient hôtel de Cherbourg, in 1787. To-day it is a butcher’s shop. Several of the houses have curious signs and other vestiges of past days. The circular colonnaded street we come to now, Rue de Viarmes, was built in 1768 by the Prévôt des Marchands whose name it bears. It surrounds the Bourse de Commerce built in 1889 on the site of the Halles aux Blés erected in the first instance in 1767, twice burnt to the ground and twice subsequently rebuilt on the site of the famous hôtel de Nesle where la Reine Blanche, mother of St. Louis, is said to have died in 1252. L’hôtel de Nesle was inhabited later by the blind King of Bohemia, killed at Crécy, and subsequently by other persons of note, then was taken to form part of the Couvent des Filles Pénitentes, appropriated with several adjoining hôtels in after years by Catherine de’ Medici (_see_ p. 9). After the Queen’s death, as the possession of the comte de Bourbon, it was known as l’hôtel de Soissons; in 1749 it was razed to the ground. One ancient pillar, la Colonne de l’Horoscope, with its interior flight of steps still stands.
