A new hour long documentary for PBS' series, Building the Great Cathedrals, explores the mystery of how, in the 15th century, Florentine architect Filippo Brunelleschi constructed one of the largest domes the world had ever seen. Winning what could be considered one of the earliest architectural competitions, Brunelleschi developed a unique system that allowed construction on the dome to occur while services were being conducted in the cathedral 100 metres below. The team in this episode model this freestanding structure in an attempt to understand just how Brunelleschi achieved such a feat of Renaissance engineering.
