I could see the Four Arches bridge from my bedroom window when I was a child. It was a good place to paddle and catch sticklebacks to take home in a jam-jar and add to the population in the old Belfast Sink that sat in the 'yard'. These days, I suspect the sticklebacks would have been happier left where they were.
Back then, at the bottom of the garden, the grass was kept mown (I'm told the same area is a mass of brambles now), and you could see humps and bumps -- some people claimed these were the tops of Anderson's shelters, and other that they were the evidence of ridge-and-furrow fields... I think ridge-and-furrow is more likely as Anderson's shelters beyond the boundary of the gardens would not have been very accessible. But whatever they were, courting couples in my teens found them very hospitable -- at the wong time of day, you had to avert your eyes as you walked from Brook Lane along the back boundary of the houses in Cole Valley Road.

The River Cole in winter, as viewed from the road bridge on Brook Lane. I'm sure my memory is unreliable, but I don't remember a lot of snow while I was living in Hall Green after the winter of 62/63, when I remember walking in channels through snow drifts that were a long way above my head. Of course, for a 4 year old, that may not be that high, but by all accounts 62/63 was a very hard winter.
Another favourite place for paddling and fishing, but very definitely only on the upstream side of the weir. Keeping your footing on the weir itself was very chancy (a slippery surface and fast flowing water) and on the other side of the weir a deep pool had been scoured. The bridge that crossed the river over the weir (not shown) had no parapet in my day; it's been renovated since and railings added, as shown here.
