Whitegate Oil Refinery in Cork Harbour, as seen from Crosshaven on the other side.
What you’re seeing here is Corkbeg Island in the foreground and this chimney stack in the background. Took me a while to figure that out! Zoom out of either map and draw a straight line through both going south west to pin point where I was standing when I took the photo 
I know this is an aside but the silver looking tanks in the shot remind me of the bold prosperity of the 1950′s in America………y’know, almost anything is possible.
