Middle Tier Compressor House, Dinorwic Quarry.

Out of the three compressor houses that I found at Dinorwic, sure there's more but this on the middle section was the one in the worst state. Each compressor house had a small smithy adjoined to it to help keep the place maintained and make repairs. Only the forge remains in this ruin and a smashed up Type 100 Compressor imported from New York, USA.
