Nobile Collegio Del Cambio (Noble College of the Money Changers' Guild), Perugia

The Nobile Collegio del Cambio is a historic seat of the Money Changers' guild of Perugia. From 1452 to 1457 the corporation of local bankers, known as "Arte del Cambio", established their headquarters at the Palazzo dei Priori in Corso Vannucci. The Guild's coat of arms – griffin above the coffer – adorns the building to this day.

The architectural design was by Bartolomeo di Mattiolo and Lodovico di Antonibo; the pictorial inner decoration – notably that of the Sala delle Adienze (Audience Hall) – was entrusted to several artists, the most famous of whom was Pietro Perugino. Inside the Hall are the series of lunettes frescoed by Perugino.

The College's main door, designed by Lodovico di Antonibo himself, was carved by Antonio da Mercatello in 1501. The wooden furnishings made by Domenico del Tasso feature the grotesque decoration used in this type of furniture for the first time.

The College Chapel of San Giovanni Battista (St. John the Baptist), built in 1506 - 1509, was painted entirely by Perugino's pupil, Giannicola di Paolo, between 1515 and 1518. In the vault, the Eternal Father is depicted among the apostles, evangelists, doctors of the Church, and the patron saints of Perugia. In the altar there is a Baptism of Christ and on the sides – an Annunciation (1515-1516). Contrary to what some may mistake for the ostentation of wealth, the lively coloring of the walls, accentuated by the great profusion of gold and lapis lazuli, is meant to brighten up the space in the absence of windows.

The collection of coin weights, displayed here, is the world's richest: containing over 550 items used for verification of coins circulated in Perugia, the Papal States and other Italian city-states between the 15th and the second half of the 19th centuries.
