Emley Moor transmitting station in Kirklees, West Yorkshire. The tallest freestanding structure in the UK at 1084 feet high, and a Grade II listed building.
Here’s a 5 minute video showing the history of the mast and the incredible view from the top.

I do love the sight of Emley Moor coming into view – whether I am on the train from London, the M1 or just turning off the A62 at Mirfield. Seeing the mast means I am nearly home even if I still have a dozen miles or more still to go.
