Piazza della Signoria
By 1821, Fenzi established the "Banca Fenzi", which was soon to branch out all over Italy and Europe. He opened a branch in "Piazza della Signoria" and from 1829 it acquired a Palazzo on Via San Gallo that was to become the "Palazzo Fenzi", that had been put up for sale after the extinction of the Marucelli family.
