Some of the monuments of the church were saved; that of the Cardinal François de la Rochefoucault, abbot of S. Geneviève, and High Almoner of France, who died in 1645, sculptured by Philippe Buister, being placed in the chapel of the Hospital for Incurable Women, of which he was the founder. The statue of Clovis, renewed in the 12th century, is now at S. Denis, owing to the accident of its having been replaced in the 17th century by a superior one in white marble, which was destroyed in 1793.[75] Another tomb, that of a chancellor of Notre-Dame de Noyon, who died in 1350, is now in the École des Beaux-Arts. The monument of René Descartes was less fortunate, for, after having been transferred to the museum of the Petits-Augustins, it was dismembered, and dispersed or destroyed; but the remains of the great philosopher were re-buried at S. Germain des Prés. Some of the conventual buildings remain and form part of the Lycée Henri IV. The tower is Romanesque at the base and pointed at the upper stories--14th and 15th century respectively. The cloisters and refectory form part of the school buildings, but they have been much modernized. The latter is an elegant structure of the 13th century, and now serves as the school chapel. In the sacristry is a large stone statue of the patroness (13th century) which formerly formed part of the central pillar of the principal doorway of the abbey church; it represents her with a demon on one shoulder blowing out her candle, and an Angel on the other relighting it. What was formerly the library is a series of galleries upon the plan of a cross, with a cupola at the intersections. It is no longer used for this purpose, all the books having been placed in the new building on the other side of the square.
