The Ordnance Survey mapped this spot as "Cross Hill" as far back as 1840, suggesting a cross of some kind once stood here and was prominent enough to name the land after. By the time the surveyors returned in 1916, the designation had quietly shifted to "Cross (Site of)", a small cartographic admission that whatever had given the hill its identity was already gone.

What remains today is a low earthen tumulus, oval in plan, measuring roughly 13.75 metres east to west and 11 metres north to south, rising between 1.6 and 1.85 metres at its highest point toward the eastern extent. A tumulus is essentially a mounded earthwork, often associated with burial or ritual use, though the original purpose of this particular example is unclear. A single loose limestone boulder rests against its eastern face, and around the sides there is evidence of field clearance rubble, the kind of material farmers push to the margins when working the land. Nettles have colonised the slopes. No cross survives, no base, no plinth, no socket stone; nothing that would explain the name with any certainty. Whether the cross was removed, collapsed, or was always more modest than the name implies is not recorded.
