The chapels are entered at the back of the San Lorenzo Church and are split into three sections: the crypt, the Cappella dei Principi (Chapel of the Princes), and the New Sacristy. More information regarding the contents of the chapels may be found here. The church also contains several paintings and sculptures. The San Lorenzo Church is one of the most important churches in Florence. It was built between 1444 and 1448 by Antonfrancesco di Antonio di Buonaventura di Lorenzo del Piero, aka Brunelleschi. The original design included a dome but this was not completed until 1511 after the builder's death. In 1773 Giuseppe Zoppino added two more floors to the dome bringing its height to 42 meters (137 feet). This was the highest dome in Italy at the time. The dome was restored in 1877 by Luca Beltranozzi and then again in 1952-1954 by Alfredo Guarneri after it was damaged by fire. Brunelleschi was an Italian Renaissance architect who designed the Dome of Michelangelo and the Great Hall at the University of Florence. He also had a role in designing the San Lorenzo Church although he died before it was complete. His son, Leonardo Brunelleschi, continued his work on the dome of the San Lorenzo Church until his death in 1446 while still in his thirties.
