To accommodate the tombs of other members of the powerful Medici, namely, for example, Cosimo I de' Medici, Grand Duke of Tuscany, the Princely Chapel was built in the 17th century. The star architects of the time, Matteo Nigetti and Bernardo Buontalenti, were the executors here. The octagonal vault is decorated with frescoes of biblical scenes added by Benvenuti in 1828.Basilica di San Lorenzo
The basilica and the old sacristy of the church was designed by another Florentine legend: Brunelleschi. It is considered an absolute milestone in Renaissance architecture and, like the rest of the complex, is worth a visit.
