The Ponte di San Francesco (English: "Bridge of Saint Francis") is a medieval segmental arch bridge over the River Aniene in Subiaco, in the Italian region of Lazio. Constructed in 1358, its single span measures 37 metres (121 ft).[1]
Other notable historic bridges crossing the Aniene include the ancient Ponte Nomentano and Ponte Salario, both of which were also fortified with a tower.
