The philosophy of an urban explorer is, Take only photos and leave only footprints.

Kingsdown Quarry or Swan Mine

This mine is in the same hill as Brown's Folly but on the other side. It is a relatively small mine but it is still possible to get lost. No rails were laid in this mine, horses and carts were used instead. The wheels of the carts form deep grooves in the floor especially on the corners where the outer wheel cut deeper than the inner one. This camber must have proved very difficult for the horses and carts.
