Ponte Sant'Angelo

Ponte Sant'Angelo, once the Aelian Bridge or Pons Aelius, meaning the Bridge of Hadrian, is a Roman bridge in Rome, Italy, completed in 134 AD by Roman Emperor Hadrian, to span the Tiber, from the city center to his newly constructed mausoleum, now the towering Castel Sant'Angelo. The bridge is faced with travertine marble and spans the Tiber with three arches; it was approached by means of ramp from the river. The bridge is now solely pedestrian, and provides a photogenic vista of the Castel Sant'Angelo. It links the rioni of Ponte (which was named after the bridge itself), and Borgo.
