The Florence Cathedral, Cathedral Santa Maria del Fiore, is the third largest catholic church in the world, and is a major landmark of Florence. It is also here that the Renaissance allegedly started in the 1400s, where the chief architect Brunelleschi successfully engineered and completed the large dome, sparking a chain of innovation and arts that prospered for the next two centuries. Today, we can climb the bell tower beside the cathedral and admire the beautifully designed dome, as well as a good view of the city of Florence.
