To the L. of the Pantheon, the library of St. Genevieve stands on the site of the College Montaigu and behind, in the Rue Clotilde, will be seen the steep-pitched roof of the old dormitory and refectory of the monastery of St. Genevieve: to our L. stands the picturesque church of St. Etienne du Mont (p. 85), whose interior is architecturally of much interest. The triforium, supported by round pillars and arches, in its turn supports a _tournee_, with another row of arches and pillars; some fine sixteenth-century coloured glass still remains. Biard's florid choir screen (p. 344) or _jube_ will at once attract the visitor, and the ever-present worshippers around the rich shrine R. of the choir will tell him that there such relics of the holy patroness of Paris as survived the Revolution are preserved. Two inscriptions near by recall the historical associations of the site. Leaving by the door this side of the choir, we issue into the Rue Clovis: opposite we sight the so-called Tower of Clovis, now enclosed in the buildings of the Lycee Henri IV., and once the tower of the fine old abbey church of St. Genevieve. A closer examination from the courtyard proves it to be partly Romanesque, partly Gothic. We descend the Rue Clovis and at No. 7 find one of the best-preserved remains of the Philip Augustus wall. Proceeding to the end of the Rue Clovis, we turn R., ascend the Rue Cardinal Lemoine, and cross to the Rue Rollin, which we descend to its intersection with the Rue Monge: in the Rue de Navarre opposite will be found the ruins of the old Roman Arena (p. 13). To return, we descend the Rue Monge, which terminates at the Place Maubert, where we find ourselves on familiar ground; or we may re-ascend the Rue Rollin, retracing our steps to the Rue Cardinal Lemoine, cross L. to the Place Contrescarpe and on our L. find the interesting Rue Mouffetard with curious old houses: 99, the site of the Palace of the Patriarchs of Alexandria and Jerusalem, is now the Marche des Patriarchs. The street terminates at the church of St. Medard, whose notorious cemetery (p. 245) is now a Square. We retrace our steps, noting L. the old fountain at the corner of the Rue Pot de Fer, continue to the end of the Rue Mouffetard, and descend by the Rue Descartes, where at No. 50 is an inscription marking the site of the Porte St. Marcel called Porte Bordet. We pass the Ecole Polytechnique, on the site of the old College of Navarre, and continue down the Rue de la Montagne Ste. Genevieve to the Place Maubert. [Illustration: INTERIOR OF ST.
