Also known as the Kazarma Bridge, this simple structure, which crosses a small gully in Greece’s southerly peninsula, may go unnoticed to some visitors. But incredibly, this stone crossing could be as old as 3,300 years, since the Ancient Greeks supposedly constructed it sometime between 1300 and 1190 BC.
