Dome Of The Florence Cathedral
The Florence Cathedral's octagonal-shaped, Brunelleschi-engineered dome has an average internal diameter of about 144 feet (44 m), making it slightly larger on average than the circular dome of the Pantheon of Rome, which had been the world's largest dome since antiquity. "Brunelleschi's Dome" was completed in 1436 and was world's largest dome until the late-19th Century; it remains the world's largest brick and mortar dome.
