Built on the edge of the Peranthi hill and the banks of the Arahthos river (which provided irrigation for ancient Amvrakia), Arta is undeniably known for its internationally famous bridge. According to the myth, the foreman's wife lays in its foundation. In 168 B.C., after the city was pillaged by the Romans, its residents fled to Nikopolis. It has been capital many times, while as ancient Amvrakia it was capital of the kingdom belonging to Pyrrhus, the king of the Molossians.
