At the south angle of the Rue Montmartre the majestic transitional church of St. Eustache towers over the Halles. We descend the Rue Vauvilliers, formerly of the Four (oven) St. Honoré, in which two of the houses still display old painted signs: others retain their quaint appellations—The Sheep’s Trotter, The Golden Sun, The Cat and Ball. Turning westward by the Rue St. Honoré, we shall find at the corner of the Rue de l’Arbre Sec the fine fountain of the Croix du Trahoir erected in the reign of Francis I. and rebuilt by Soufflot in 1775: here tradition places the cruel death of Queen Brunehaut. Lower down, where the street intersects the Rue de Rivoli, an inscription on the corner house to the left marks the site of the Hôtel de Montbazan, where Coligny was assassinated, and yet lower down the Rue de l’Arbre Sec we note the Hôtel des Mousquetaires, the dwelling of the famous D’Artagnan of Dumas’ Trois Mousquetaires, opposite the apse of the church of St. Germain l’Auxerrois. After examining the interior of the church, especially the beautiful fifteenth-century Chambre des Archives, and the porch of the same date, we are brought face to face with the principal entrance to the Louvre.
