Ponte Sanguinario: Italy's hidden Ancient Roman bridge

Ponte Sanguinario is a historical monument found in the easter part of Piazza della Vittoria, Spoleto. It is believed to have been constructed as part of the Via Flaminia, a Roman road, between 27 BC and 1st century AD. The bridge, built with large squared blocks of travertine, features three semi-circular arches, of which two are visible. Ponte Sanguinario allowed the Via Flaminia to cross the Tessino River, but the river's gradual shift in bed rendered the bridge's original function obsolete by the end of the 14th century. The bridge was rediscovered in 1817, having been hidden due to alluvial deposits that raised the surrounding road level. The bridge was discovered during public works carried out after the restoration of the Papal States, when it was decided to build a bridge over the Tessino River.
