The picturesque square of San Lorenzo is very popular thanks to the typical local market, located close to the Basilica of San Lorenzo.
This Piazza is dominated by the Basilica of San Lorenzo behind which there is the dome of the Cappella dei Principi. Realized in 1423 on a fourteenth century church, the Basilica of San Lorenzo was designed and built by Brunelleschi on demand of Giovanni Bicci. The Master produced an innovative project, dramatically different from the classical style of churches, with their almost mystical lighting, creating a church where the light is allowed to penetrate and illuminate all of the building's architectural features. The internal façade, the sacristy and library were designed by Michelangelo. Inside the Basilica of San Lorenzo one finds the works of Desierio da Settignano, Donatello, Rosso Fiorentino, and Bronzino. The Old Sacristy is the work of Brunelleschi, whilst the New Sacristy was realised by Michelangelo; the latter houses the tombs of the members Medici Dynasty, hence it is also called the "Medici Chapel". The Laurenziana Library, situated to the left of the Basilica di San Lorenzo was also the work of Michelangelo, commissioned by the Medici Family.
