Crumbs! That took me a long time to read
As a young lad (born in 1941) I spent considerable time exploring old air-raid shelters etc, and later on in life worked on many ex RAF sites (converting them to business parks/shopping centers/industrial sites etc), and always found them 'interesting'. The same went for any older properties due for demolition during the 'urban re-developments' in Bradford around the 60s - 70s.
One of my local bike 'saunters' includes this area
which is on part of the old WW2 RAF Skellingthorpe site. Most of the RAF stuff has been cleared away now, but there's still a few reminders of what once was there - massive earthen banks (blast walls), concrete floors and footings, concrete-slab covered conduits etc, all gradually being reclaimed by the natural woodland re-growth (occasionally assisted by human management). It's a pleasant place to while away a bit of time
with a varied selection of flora (and fauna)
Some 'lumpy' bits
('lumpy' bits of this type are not 'natural' around here - especially when there's a large rectangular concrete pad on top).
One can even see clear evidence of what once was here
including this
There's a few places where bricks have been removed, but as the walls seem to be thicker than three bricks none of the walls are actually pierced.
Here I am wondering if it's worth nipping back with a long chisel and lump hammer
