The Palazzo Vecchio is the central landmark, with a fortress-like appearance and an imposing clock tower. Next door is the Loggia dei Lanzi, an arched walkway that hosts a number of Renaissance-era statues, while there are a collection of cafes with outdoor seating to give you that much needed breather after a day of sight-seeing. Also of note are the four palaces on the L-shapes piazza and the entrance to the street dedicated to the Uffizi Gallery.
Despite its position as a place for tourists to cram in and mill about, the Piazza della Signoria has plenty of open space, amazing outdoor works of art, and an exciting atmosphere nearly any time of day. Can you think of anything better to do with your time in Florence?
