The Basilica di San Lorenzo was the parish church of the Medici Family. Members of this wealthy and powerful family were entombed here. The church, originally designed by Filippo Brunelleschi in the fifteenth century, is an early example of ecclesiastical Renaissance architecture.The Basilica di San Lorenzo is one of the oldest churches in Florence and its origins can be traced back to the late Roman era. It was the parish church of Florence's most powerful families, the Medici, who would for generations continue to embellish the church. Its current appearance goes back to 1419, when Giovanni de' Medici (Cosimo the Elder) commissioned Brunelleschi with a reconstruction of the church. Brunelleschi died before the reconstruction was completed and many other architects worked on the church, based on Brunelleschi's original Renaissance design.
