Here is the second of the photographs taken from the top of Beacon Hill, Halifax in the early 1970s. My camera has swung around, so now I am looking in the direction of The Shay and Savile Park. You can just make out the three graces – St Jude’s Church, Crossley Heath and Wainhouse Tower – on the near horizon. Just as with the last of these photographs taken from my “1970s drone” you can focus in on particular areas and see how things have changed in the last half century or so. You can see where houses weren’t and where mills and factories still were. You can see that the Building Society headquarters has made it through the historical cut, but Eureka hasn’t. It is the kind of picture you could set an exam on, write a book about or compose a sonnet to.
