You would need ground penetrating radar to detect something as large as you are suggesting as it would be deeper. Underground implies under many feet
of earth. You may be mistaking the ancient outlines of an above ground settlement. Thats now outlined
ABOVE ground.
Now....if you'd rephrase your O.P. to say "outline of possible ancient settlement"...I'd go with that. But using Google Earth, it certainly isnt an
under-ground anything. A covered over above-ground? Possibly. Even probably.
There are remains of many, Roman, Saxon, Norman etc... points of habitation still there under a few feet of topsoil. I thought you meant a tunnel to a
cavern to a cave of sorts, mine etc..and down there, discovered an under-ground city.
Im pretty sure its not under-ground. Outlines of settlements have been found for years now...but above ground, under layers of countryside and crops.
