This picture is of the Trevi Fountain (tre meaning three
in Italian, and via meaning road; the Trevi Fountain is located
at the intersection of three roads). The Trevi Fountain was built by Nocolo
Salvi in the 18th Century, and depicts Neptune's seahorse drawn chariot.
Many movies have used scenes at the Trevi Fountain and popularized the
notion that if you throw three coins in the
fountain, you will return to Rome.
