The Boulevard Saint-Germain was the most important part of Haussmann's renovation of Paris (1850s and '60s) on the Left Bank. The Boulevard replaced numerous small streets which approximated its path, including, from west to east (to the current boulevard Saint-Michel), the Rue Saint-Dominique, Rue Taranne, Rue Sainte-Marguerite, Rue des Boucheries and Rue des Cordeliers. One landmark removed to make way for the project was the prison of the Abbey of Saint-Germain-des-Prés which stood entirely on what is now the Boulevard, just west of what is now the Passage de la Petite Boucherie.
