Brunelleschi's construction of the _____________ was revolutionary in architecture.

• A. Pantheon
• B. Dome of the Florence Cathedral
• C. Colosseum
• D. Hagia Sophia

Answer: (B)

The main idea being tested is a turning-point in architectural engineering when a massive dome could be built for a great cathedral through innovative methods. Brunelleschi’s dome for the Florence Cathedral redefined what was possible by creating a self-supporting, double-shell brick dome that spans a large octagonal opening without heavy external supports dominating the interior. He designed an inner and outer shell linked by ribs and a clever brickwork pattern—often described as a herringbone lay—that locks each course in place and distributes weight outward. This approach allowed construction to proceed without the long, cumbersome centering used on earlier domes and produced a lighter, more durable structure that could rise to a dramatic interior height and a striking exterior silhouette. The result set a new standard for engineering in architectural design and influenced future Renaissance domes across Europe.
