These cooling towers in Sheffield are all that is left of a once huge power station. The M1 motorway curves past them and these towers served as a landmark on the journey north to visit friends and family. They are like silent sentinels welcoming you to Yorkshire and reminders of the area's industrial past. It was only when I reached these towers that I felt I had reached the north and my journey was near it's end. I have just learned that they are scheduled for demolition. There are proposals being put forward to make use of the towers but it is possible that one day I will travel up the M1 and they will be gone. That would be a shame.
