Geolithology and provenance of the materials of the historical buildings and monuments in the centre of Florence (Italy)

Two especially important and meaningful areas from the historical point of view have been considered in this work. Piazza della Signoria presenting Palazzo Vecchio and many other outstanding buildings, is a typical example of the use of sandstone materials characteristic of the Florentine area; Piazza del Duomo with the Cathedral of Santa Maria del Fiore standing in the middle is, on the other hand, an example of other equally typical lithotypes such as the “white” marble and the “red” and “green” “marbles” that decorate the Cathedral. A detailed study, the relief and the mapping of the historical buildings in Piazza della Signoria and of the Cathedral of Santa Maria del Fiore have lead to the description of the materials that make them up as well as to the establishment of their quarry provenance.
