Pont du Gard, France
from MS Maribelle Photos

Roman aqueduct

To grasp the scale of the Pont du Gard, look for the people on the bridge behind the second row of arches. (The bridge was constructed next to the Roman aqueduct in the 18th Century.)

The stone protrusions on the aqueduct's face were used to hold scaffolding for Roman craftsmen and slaves. Every stone was cut to a plan and hauled to the site over a great distance, where it was then lifted into place with the help of a block and tackle.
