Is it a local cave, for local people?

That's pretty neat, incredible what 3D scanning technology is capable of now. I wish more historic sites would do this, particularly the less accessible ones. The British Museum is planning to 3D scan its entire collection after the recent scandal with the stolen artefacts.

There's a free iPhone app called Scaniverse that can do 3D scans of objects and rooms, it's not quite as good as the tech used here but still fun to play with.

Royston Cave is an interesting place. The UK has a few mysterious subterranean places, like the Shell Grotto in Margate.

Cool. TY
