Trajan's Bridge, Chaves

Trajan's Bridge in Chaves is a Roman granite bridge spanning the Tamega River in northern Portugal, constructed at the end of the 1st or beginning of the 2nd century AD under Emperor Trajan. The bridge features twelve visible arches with six additional arches hidden beneath riverbank structures, extending roughly 150 meters. Two inscribed columns on the bridge pay tribute to Roman emperors; the originals are now in the Museum of the Flavian Region. Until the 1950s it was the only river crossing in Chaves and is now entirely pedestrian.
