Aerial view of Arbor Low Stone Circle and Gib Hill, Derbyshire; the region&#x27;s most important prehistoric site, Arbor Low is a Neolithic monument atmospherically set amid high moorland. Within an earthen bank and ditch, a circle of some 50 white limestone slabs, now fallen, surrounds a central stone &#x27;cove&#x27; - a feature found only in major sacred sites. Nearby is enigmatic Gib Hill, a large burial mound.
