hahaha... Im dying to get an excavation going :)!!!!! seriously tho!
Im trying to muster the energy to go and do some research on it.
I dont think it was originally used as a petrol dump as it appears on the map of 1893... not much petrol going about then! Also, if the Queenie was a target for the Germans, why would we be dumping petrol there... so close to my house!!!
Theres no indication of it being lead-lined although most of its buried. There are some strange pieces of stone lying about in the undergrowth. You can tell the stone has been worked, and theres also some marble-like pieces lying around. I dont think the are marble, they look more like those transluscent chukkies you get for ur driveway.
Also, the old pond (on the NLS map) has been partially filled in Im assuming with the debris from the buildings around there. Theres also a wee dilapidated bridge that looks as though some recylcled stone's been used for the foundations.
Im away to call in Tony Robinson!
