If you haven't discovered it yet, National Geographic magazine's Our Shot is one of the best daily photo gallery sites on the web. Their photos are always fantastic and cover a wide berth breadth of subjects.
Case in point, this photo of an aqueduct built by King Herod during the first century B.C. to carry water from a lake across 17 miles of desert into the ancient city of Caesarea (present day Israel). Michael Melford took this fantastic shot by moonlight.
