I must say, when this debate appeared on the order paper, I was intrigued by the title of the debate and I've enjoyed the opportunity we've had this afternoon to share some of our memories, in some cases, but also our ambitions and aspirations for reinventing the communities in which we live. Because when I think about the industrial architecture or the industrial infrastructure that I grew up with, it speaks to us of who we are as a people today.

I grew up and went to school in the shadows of the Sirhowy ironworks, one of the biggest ironworks in Wales, when it was established at the end of the eighteenth century. I played rugby and football on fields in the shadows of the nine arches, which, of course, carried the Heads of the Valleys railway from Tredegar to Merthyr and then down to Abergavenny. And what it did, of course, was to tell us not just of the big, massive, global economic forces that shaped the economy of south Wales, but it also taught us about how we are linked and connected to each other. I think, in all sorts of different political debates, all too often we try to focus on those things that divide us from each other, but what our industrial infrastructure tells me is how we're all linked together. We spoke in a debate earlier in the year about how the Bryn Oer tramroad links Talybont in Breconshire with Trefil and with Tredegar, but look across a couple of Valleys into Brynmawr, and you also have the Disgwylfa tramroad, which took materials from the Llangattock quarries in Breconshire, again, in the Usk valley, to Nantyglo and which Bailey used then in making iron in creating the Nantyglo ironworks. These are important linkages that exist today. I can cycle along the Bryn Oer tramroad, I've walked along the Disgwylfa tramroad, and you can understand our history and understand who we are as a people and a community.

Last Friday, I was lucky enough to join a group of residents from Llanhilleth who had reopened somewhere called Granny's Wood. Now, the granny in question's name was Margaret Griffiths and she enabled her grandchildren, who were there last week, as it happens, to play on an area of land that had previously been the Llanhilleth quarry. If you walk down—you don't find it unless you're looking for it—from the old pithead baths to where the shafts actually were, the old pitheads down the Burma road, as they described it, that the colliers would walk up, of course, at the end of the shift, and then along the pathway that miners would walk on to and from work when the Llanhilleth pits were at their height, of course, there would have been hundreds of men walking back and forth there every day. Today, it's a peaceful and tranquil and rediscovered part of our heritage and our places, and I hope that we'll be able to look towards ensuring as part of the Valleys Regional Park that these experiences, these places, these histories and these linkages become part of who we're going to be as well.

The understanding of history, I believe, is absolutely fundamental to the future of public policy. When I think about how these different tramways, railways and roads have linked us, I also think of something else, which is a much older form of transport, of course, and that is our rivers. It hasn't been mentioned in the debate this afternoon, and our rivers, particularly in south Wales, rarely are, but if you ever speak to Councillor Malcolm Cross in Tredegar, he will talk about how he believes that the rivers of south Wales are our great neglected asset. And, do you know what? I think he's right. If you look at Vale Terrace in Tredegar, it's built facing the river because the river at that time was one of the primary forms of transport, before we used canals and—. I'll take an intervention.
