Cym Dyli Power Station, Nant Gwynant

Nestled on the lower flank of the Snowdon / Yr Wyddfa Massif, the Cwm Dyli Power Station, Britain’s oldest grid-connected hydroelectric plant, was originally built in 1905 to power the slate industry. Built by the Porthmadog, Beddgelert and South Snowdon Railway Company, it now feeds 9.8 MW of green energy to the National Grid, drawing water from Llyn Llydaw further up in the mountains. Known as the 'chapel in the valley' for its striking architectural design, this local landmark is instantly recognisable to visitors to Nant Gwynant and has become an integral part of this beautiful valley. 

The photo was taken during a brief break in a rainstorm as summer collided with autumn, giving the photo a suitably atmospheric feel. I got soaked through and nearly blown over by an unexpected gust of wind, but I think it was worth it!
