|Pont du Gard|
In 1743 a second bridge was built alongside the main aqueduct to allow for heavier cart and foot traffic. Maggie and I walked across this bridge to view the aqueduct from the other side and then to climb up to view the very top...
As well as being quite a beautiful structure.
If you visit, be sure to spend some time in the wonderful museum onsite. It's included in the price of admission and is well worth an hour or so of your time. You'll be amazed to learn just how they built this huge structure.
