I found if very interesting to read about the history and architecture of the Dome of Florence Cathedral. I have traveled to Florence and spent some time at the Duomo. It is truly a work of art, with all the intricate details on the exterior as well as the frescos inside. There are several marble statues tucked into arches and corners on the outside of the Cathedral. I am sure that when I visited the Duomo, they provided some back history, but I did not realize all the work that went into constructing the Dome. Seeing that I work for a Structural Engineering company, I found this revolutionary feat of engineering to be amazing as well as informative. Brunelleschi revolutionized the way structures were built with this project, by creating a double shell of masonry 138 feet across supported by 24 ribs or rafters. Brunelleschi also devised a system where tempory wooden supports were cantilevered out of the drum, allowing him to move these supports up as the building progressed, allowing each portion of the structure to reinforce the next one. Thanks to this new form of architecture/engineering, when completed, the unit required no external support to keep it standing.
