Construction Process
Innovations and Contributions

Innovations and Contributions

Brunelleschi came up with several innovations and has some major contributions to his credit like inventing the ox-driven hoist machines to carry the immensely heavy stones up to the construction level. He also employed a unique herringbone pattern to construct the brick walls of the Dome so the bricks would reinforce themselves and not fall off the wall. He also invented an amphibious boat to transport large marble pieces to the cathedral without causing them damage.

Innovations and Contributions

Challenges Faced

Building the Dome was not an easy task. Nobody knew how to construct a dome atop existing walls. Then, there was also the problem of constructing a vault above the dimensions of the octagon. It was Brunelleschi who came up with the idea of building two domes - one inside the other. this  idea of constructing an inner and outer dome for the Florence Cathedral's dome allowed for a lighter and more stable structure, which helped prevent the dome from collapsing over the centuries.

Brunelleschi’s Dome was the largest ever masonry dome to be built in the world at the time. It does not have a supporting structure.
