The Pazzi Chapel was designed by Brunelleschi as a grave chapel for the wealthy Pazzi family. It is a prime example of early Renaissance design with balanced proportions and slick grey-white overtones suitable for a grave chapel.
The basic design is inspired by Brunelleschi’s Old Sacristy in San Lorenzo, but here he had to work within the confines of an existing building. The columns are thus simply style elements — the roof is carried by the existing monastery walls.
