The Palazzo Medici-Riccardi was built by Michelozzo in 1444 for Cosimo de’ Medici il Vecchio; it’s the prototype Florentine palazzo, on which the more overbearing Strozzi and Pitti palaces were later modeled. It remained the Medici private home until Cosimo I officially declared his power as duke by moving to the city’s traditional civic brain center, the Palazzo Vecchio. A door off the courtyard leads up a staircase to the Cappella dei Magi, the oldest chapel to survive from a private Florentine palace; its walls are covered with dense and colorful Benozzo Gozzoli frescoes (1459–63) in the International Gothic style. Rich as tapestries, the walls depict an extended “Journey of the Magi” to see the Christ child, who’s being adored by Mary in the altarpiece.
