Santo Spirito Church
The external façade of Santo Spirito remained in rough stone until the 18th century, when it was plastered over. The internal façade was completed by Salvi d’Andrea (1483-87), and it still has the great 15th-century stained glass window of Pentecost, made to a design by Perugino.
In 1489 work began on the Sacristy, designed by Giuliano da Sangallo and continued by both Antonio del Pollaiolo and Salvi d’Andrea. In 1497 the vestibule was completed, with its most beautiful coffered barrel vault, to a design by Simone del Pollaiolo known as Cronaca. Although altered by later architects, the church of Santo Spirito retains the extraordinarily innovative structure that Brunelleschi planned, with its thirty-eight niche-chapels and its Corinthian colonnade, of evidently classical inspiration, running all around the nave and transept.
