How’s this for a comparison of structures spanning the same valley? The Meldon Viaduct, once carrying trains from Dartmoor out to Exeter and beyond, lightly touching the ground far below on its delicate, ethereal legs. Looking the other way up the valley, the brutal dam wall of Meldon Reservoir takes up the same profile: in its own way strangely beautiful and behind it an unfathomable number of bathtubs full of water. They both occupy the same V shape, but couldn’t be any more starkly different, and create completely contrasting effects on the moorland valley. Beautiful family-walking and a dip today in the pool at the bottom of the valley.
