A cathedral that has stood for centuries has seen a great deal of turmoil. During the Reformation, the cathedral became a Protestant church, and Strasbourg, a printing capital, became a center from which reformers spread pamphlets and hymn books. Protestant and Revolutionary iconoclasm, as well as the war periods of 1681, 1870 and 1940 to 1944, took a toll on some of its finest features, including the choir screen of 1252 and the successive high altars of about 1500 and 1682. Some treasures and fragments are displayed in the Musée de l'Œuvre Notre-Dame. In the Franco-Prussian War of 1870, projectiles set fire to the roofs of the nave and the choir. During the First World War, all the bells except the great heavy one were removed. In the Second World War, the cathedral's stained glass windows went on a journey of their own. The French first hid them in southwestern France, then they were carted to northern Germany, and finally they were saved and returned by the Monuments Men, the British and American troops dedicated to returning art to its rightful place after 1945. Inside, you can still admire works that endured, such as the pulpit carved from white sandstone in 1486 and a baptismal font in the north transept, sculpted in 1453 by Jost Dotzinger.
