While the question does not specify which "Notre Dame" cathedral is meant (because there are many cathedrals with this name), the name "Notre Dame" indicates that it is a church dedicated to "Our Lady" (which is what the French phrase means.) "Our Lady" always means "the Virgin Mary, mother of Jesus Christ." Thus, the patronal saint of a cathedral named "Notre Dame" would be St. Mary, the mother of Christ.
la Sainte-Chapelle and many gothic churches can be found in Paris. The Notre-Dame cathedral is also built in Gothic style.
The bells of Notre Dame ring every Sunday. This is because God has his day of rest. It rings many times for a celebration like Easter or Christmas day.
Notre Dame simply means our lady, so there are many churches devoted to the Virgin Mary called Notre Dame (Notre Dame de Chartres, Notre Dame de Rouen, etc.). The most famous Notre Dame Cathedral (with the Hugo story and Disney movie and all) is located in center of Paris.
