Notre-Dame Cathedral is a living chronicle of medieval France, demonstrating the architectural styles, decorative elements, and religious symbols of that era. It embodies the essence of medieval France—the country of classical medieval times. However, during the 18th-century French Revolution, the cathedral began to fall into decline. Victor Hugo wrote the novel «The Hunchback of Notre-Dame,» emphasizing the interconnection between literature, historical events, eras, human emotions, and architectural masterpieces.
