We hear a lot these days about the changing nature of town and city centres, but the centre of gravity of our conurbations has never been static. I took this photograph over fifty years ago from the waste land at the bottom of Woolshops in Halifax. Widespread demolition had already swept through the narrow streets, terraces and workshops of - what was traditionally - the heart of the town, leaving vacant lots and uninterrupted lines of sight to the town abattoir. The retail footfall rarely got down this far back in those days, preferring the wider prospects of Commercial Street and the like. And then things changed: development came, new stores and car parks were built, and the abattoir and cart would more likely to be the name of a rather select bar than a description of what could be found outside.
