The view from the top of the Pont du Gard is well worth paying the extra for, especially when it gives you the chance to catch the distinctive shadow of the aqueduct spreading across the valley. The quarry for the aqueduct is just beyond the building in the centre of this shot - and this means they had to work out a way of floating the enormous stone blocks upstream to the building site. It is just staggering to consider the engineering quality and expertise that went into building this, a very long time before laser measurers and JCBs!
