The Basilica di San Lorenzo is one of the largest churches in Florence, Italy which was consecrated in 393 by Saint Ambrose, Bishop of Milan. It used to give three distinguished experiences as it had three sections, Basilica, the Medici Library and the Medici chapels. The present building was designed by Brunelleschi and was re-built between 1421 and 1461.
The facade of the basilica is also further divided into three sections. The central section contains the doorways and windows, while the two side sections are occupied by a series of fourteen marble statues of saints and prophets.
The interior of the basilica is divided into a nave and two aisles, separated by a series of columns. The nave is barrel-vaulted, while the aisles are groin-vaulted. There are several artworks and artifacts contained within the Basilica di San Lorenzo, including Michelangelo's "Pietà" and Brunelleschi's octagonal "Baptistery". The basilica has a long and complex history, with a number of religious figures having been associated with it over the centuries. These include Saint Ambrose, Saint Augustine, Saint Jerome, and Pope Leo I. The church has also been linked to a number of important political figures, including the Medici family and Cosimo de' Medici.
