In addition to the cathedral, Strasbourg houses several other medieval churches that have survived the many wars and destructions that have plagued the city: the Romanesque Église Saint-Étienne, partly destroyed in 1944 by Allied bombing raids, the part Romanesque, part Gothic, very large Église Saint-Thomas with its Silbermann organ on which Wolfgang Amadeus Mozart and Albert Schweitzer played, the Gothic Église protestante Saint-Pierre-le-Jeune with its crypt dating back to the seventh century and its cloister partly from the eleventh century, the Gothic Église Saint-Guillaume with its fine early-Renaissance stained glass and furniture, the Gothic Église Saint-Jean, the part Gothic, part Art Nouveau Église Sainte-Madeleine, etc. What style of building is the Ancienne Douane?
