Final answer:
The Cathedral of Notre-Dame, Reims features Gothic architectural elements such as tall, narrow details, pinnacles, and a gallery of royal statues, all promoting an upward movement and grandeur that is typical of Gothic cathedrals.
Step-by-step explanation:
The exterior of the Cathedral of Notre-Dame, Reims is an exemplary display of Gothic architecture, characterized by features such as tall, narrow details, and upward movement emphasized by the use of pinnacles. The portals of Gothic cathedrals, like the one at Chartres mentioned in the reference material, often include sculptures and are angled inward, inviting worshippers inside. The facade would typically consist of a series of levels or stories, which at Reims include a gallery of royal statues that blends with the architecture's third story. Additionally, the flying buttresses, a distinctive element of Gothic cathedrals, provide crucial support for the stone roofs while creating a sense of openness and light within the structure.
