One of the most spectacular and historically interesting Roman sights in central Italy is the Roman bridge of Augustus at Narni in Umbria, Italy. The bridge spans the Nera river and was one of the largest bridges in the Roman Empire. Jean-Baptiste Camille Corot famously depicted it in a painting of 1826.
The bridge at Narni is one of several fine Roman remains to be found in Umbria. Another is Carsulae Roman ruins where the via Flaminia and the principal buildings can easily be made out. Since Umbria is closer to Rome than is Tuscany and Umbria is also traversed by the Via Faminia, not surprisingly there are many more Roman sights there than there are in Tuscany. Nevertheless, Volterra and Fiesole in Tuscany are the locations of fine Roman theatres, and the remains of the Roman theatre beneath the Palazzo Vecchio in Florence can be visited.
