What a complete change of atmosphere down here at the bottom of the gorge! The noise of the town is completely drowned out by the cascades of water. The sound is echoed off these tall stone cliffs and massively impressive viaduct arches.
Take a look at their stonework and then back at the rock face. Yes, it is indeed the same kind of rock, a tough sandstone. All of it was quarried right here. What would have been a much narrower gorge has been made wider from quarrying, leaving quite a smooth surface – now a proper challenge for local rock climbers.
One of this sandstone’s features is variability; some of it is coarse-grained, suitable for those massive blocks in the pillars, while elsewhere it is fine-grained and ‘flaggy’ – in other words it can be split into thin slices. Stone floors and even roofing slates for houses and mills could be made from this type.
