One of the best random finds yesterday coming home was a Roman aqueduct. I was coming down over the hill through the village of Ansignan and passed a sign to "Roman Aqueduct" at about the same time as I realised I was looking at it down over the hill.
This needed a closer look so I turned around and followed the signs to the little parking area nearby, passing the aqueduct as I did.
I walked down alongside the aqueduct toward the river it crosses, and saw the archways through the structure.
Not only does it carry water over the river, but it also includes a foot bridge!
Yes, that’s right - *under* the aqueduct part, you can walk into one of the arches and the structure is ‘hollow’. Turn to follow the aqueduct and you can walk under it, and over an integral bridge across the river.
Amazing design, and not only still standing but still in active day-to-day use: it’s on a cycle path and the bicycles can cross on it (not sure I would have risked taking Beaky through…)
