The Malatesta Temple, Cathedral of the diocese since 1809, is a famous example of Renaissance architecture and maybe the most illustrious monument of Rimini. It was built by Leon Battista Alberti as a precious marble casket around the gothic church of St. Francis.
The work, wanted by Sigismondo Malatesta, Lord of Rimini, started in 1446 and ended in 1460, though uncompleted. Recently, the church has been thoroughly restored. Inside, it keeps a Crucifixion by Giotto, a fresco by Piero della Francesca, bas-reliefs and sculptures by Agostino di Duccio, and a painting by Giorgio Vasari.
