The church of Saint Francesco is one of the most important monuments of Rethymno. It was the main temple of the Monastery of the Francesca Order. The architecture of the building and its ornaments are very interesting. Next to the east side of the temple two deserted chapels are preserved. Its main doorway is impressive, with capitals of composite order. During recent excavations around the church valuable archeological findings have been discovered, including two tombs of Venetian nobles.
