Florence Cathedral: The Dome They DIDN’T KNOW How to Build

Florence built a cathedral with a vast opening no one knew how to close. This episode follows Brunelleschi's solution: a dome that could rise without full centering, using geometry, brickwork, machines and nerve. Building Giants reveals how the world's boldest landmarks were imagined, engineered and built through clear visual storytelling and realistic matchstick-model reconstructions.
