Up above Derwentwater there is a tiny hamlet and tarn; both called Watendlath. Great name! And when I first went there 50 years ago it was a run down fairly derelict little hamlet. But time and tourism march on and it has been smartened up and there are, inevitably, a couple of tea shops, yet the essential character remains, a sheep farming hamlet built out of local grey slate … but you have to pay £3 to park there now. And this pretty bridge is where the tarn flows out into the stream that eventually drops down to the lake. It is a pack horse bridge and hints at a more industrial past. The Lake District has (or had before they dug holes into poor Gaia) mineral wealth; copper, tungsten, lead, and where this is lead there is silver. And paths and cobbled roads were built for packhorses to drag laden carts to smelters and ports, so they had to be strong, and this pretty shape is strong. And the classic histories say the mining only goes back to the 18^th century; but I don’t believe it. The Romans were very interested in the area with forts at Ambleside, Hardknott and Ravenglass plus many cobbled Roman roads and routes. And the Romans did not visit and fortify places for the pretty scenery; they were hungry for mineral resources and preferred to take rather than buy. So does this route go back that far; who knows; only Gaia perhaps.
