We climbed to the top of the aqueduct to view the conduit.
Visitors can only enter the conduit of the aqueduct on a guided tour
The aqueduct has a gradient of 25 cm per km for a distance of 50 km which was an engineering feat
The conduit has been broken over time
This is a tunnel to the other side of the hill; not the conduit
We climbed further up the hill
We flew the drone again
