Again and again the church of Saint-Germain-des-Prés has been restored: as in 1644, in 1820, at the time of the Restoration, and finally under Napoleon III. The choir preserves intact the style of the twelfth century. Among the tombs may be seen the tomb of King Casimir of Poland, who, after becoming a monk, was made abbé of Saint-Germain, and died holding that office in 1672. In a chapel on the opposite side of the church is the tomb of Olivier and Louis de Castellan, who fell in the service of Louis XIV., and a little further on the chapel of the Douglases, many of whom served in the Scottish Guard. Here too are the remains of Boileau and Descartes. The sacred pictures around the choir and the nave are the work of Hippolyte Flandrin, the most celebrated among the pupils of Ingrès, who died before completing his work, and to whom, in the church he loved to decorate, a monument in white marble has been erected, surmounted by his bust. [Illustration: THE TOWER OF SAINT-GERMAIN-DES-PRÉS.] It must not be forgotten that during the greater part of its history the ancient church of Saint-Germain-des-Prés was outside Paris, which gradually grew towards it and at last surrounded it. On the 2nd of November, 1589, Henry IV., besieging Paris, went up the convent tower, accompanied by a single monk, to examine the situation of the town. He is said to have afterwards gone round the walls of the cloister. But he did not enter the church, and he withdrew without uttering one single word. Saint-Germain-des-Prés was at one time known as the Church of the Three Steeples. These were destroyed in 1822 under Louis XVIII. as a measure of economy, since it would otherwise have been necessary to restore them.
