Impressive
After Segovia Aqueduct few aqueducts will impress you, but I have no doubt that the Pont du Gard will. Not just because of it's location in a valley, but also for it's good state of preservation and the possibility of walking, if you sign up to the group tour, to the third tier of arches, the top, where water once flowed and 49 feet high! This aqueduct was built around the year I to carry water 50 miles to Nimes, and it was built well because it was in operation for 500 years. Hopefully existing buildings meets the warranty!
