The dome that crowns Florence’s cathedral of Santa Maria del Fiore is six centuries old, stands 40 stories high, is made of more than four million bricks, and weighs about the same as a modern cruise ship, but how did the largest masonry dome on earth come to be? NOVA takes on the Renaissance marvel–and its maker, Filippo “Who needs buttresses?” Brunelleschi–in Great Cathedral Mystery, which premieres Wednesday night on PBS.
