Yes, they are my earliest memories. Back then, the home was alive with dozens of children of all ages and nuns hovering about supervising everything. The house and grounds seemed much larger then, of course. I got in incredibly easily when I visited last year. The site was even less secure before the fire. One could easily sneak through the side of the security fence and the front door of the house was wide open. I even came away with a memento; a stair rail, which is now sitting in my house. There were piles of them out front. There may be other former children's homes in this state, though most homes from that era seem to have long since been converted into private properties of various kinds.
I've looked at your website before and got photographs of West Cheshire Mental Hospital from when it was derelict. It was the home of my mother at the same time as my brother and I were at Knolle Park. I'm pleased you are recording some of these places as so many people have memories of them.
