The loggia was commissioned in 1423 by Braccio Fortebracci da Montone, condottiere and lord of Perugia, who had it connected to his nearby residence, which today no longer exists. Said to be the work of Fioravante Fioravanti from Bologna, it preserves four of the five original arches, one partially closed, supported by octagonal columns. Below the first, on the right, are the remains of the base of the bell-tower of the early cathedral, as well as a stretch of wall in Etruscan-Roman travertine blocks. On the left hand wall is the Pietra della Giustizia (Stone of Justice), (the original is in the Palazzo dei Priori), with which the Municipality of Perugia in 1234 declared public debt to be cancelled and ordered citizens to be taxed according to a town census. In addition there are the Perugian foot and “mezza canna” units of measurements.
