The Portinari Chapel (Italian: Cappella Portinari) is a Renaissance chapel at the Basilica of Sant'Eustorgio, Milan, northern Italy. Commenced in 1460 and completed in 1468, it was commissioned by Pigello Portinari as a private sepulchre and to house a silver shrine given by Archbishop Giovanni Visconti in 1340 containing the relic head of St. Peter of Verona, to whom the chapel is consecrated. The architect is unknown, the traditional attribution to Michelozzo having been succeeded with equal uncertainty by attributions to either Filarete or Guiniforte Solari, architect of the apses of the Certosa di Pavia and the church of San Pietro in Gessate in Milan.
