From a distance, the grey concrete structures of Catagunya Dam made me think of Russia’s Stalinist architecture with its solid and functional masses.  Up close I found nothing pretty about the Catagunya Power Station; just a very large box at the end of a wide driveway.

There was little to see looking down along its side.

So I was delighted when two cars drove down the road towards the Station. The front door was opened and I was invited inside.
