| Comments: |
Ponte Salaro is a bridge over the Aniene near the point where it meets the Tiber, on the road Via Salaria linking Rome with the middle Adriatic Sea (from which the Romans obtained salt, hence the name). Corsi’s breccia di Ponte Salaro may have been the building stone. The bridge was destroyed by French troops in 1867 attempting to keep Garibaldi from the City of Rome. A nearby tower shown in a plate by Guiseppe Vasi in the 18th century does still stand, and a modern image suggests this may be a conglomerate.
