Alcántara Bridge
Alcántara Bridge (also called Puente Trajan at Alcantara) is a Roman stone arch bridge. It was built over the Tagus River, Alcántara, Spain between 104 and 106 AD. The Roman emperor Trajan ordered this bridge built in 98 AD.[6] The Alcántara Bridge was built at the expense of 12 local municipalities in Lusitania. The names were added on an inscription on the archway over the central pier.[7]
