The Basilica di Santa Maria del Fiore is a good example. One of the most fascinating things about this cathedral was that they had no idea how they were going to build the dome when they started building it (the construction techniques weren't advanced enough at the time). They had faith that someone in a later generation would figure it out. That person turned out to be Filippo Brunelleschi, one of the greatest engineers of that time. http://en.wikipedia.org/wiki/Florence_Cathedral http://en.wikipedia.org/wiki/Florence_Cathedral
