From the 14th century, the entire block, as far as No. 104, belonged to the College of Merchants, one of the most important guilds in the Municipality of Perugia. Once a hospital for the poor, as the inscription above the central entrance shows (1507), it was until recently (1990) a public dormitory. Above the entrance is a stone inscription of the symbol of the College: a griffin above a ball of wool. In the recently restored Sala del Granaio are the traces of early decorations.
