This is a ring barrow, a type of funerary earthwork typically associated with the Bronze Age, in which a low central mound or platform is enclosed by one or more concentric ditches and banks. What makes the example at Hill's-Lot quietly compelling is not its scale but its layered geometry, a series of rings within rings, each one a deliberate act of enclosure around whatever or whoever lay at the centre.

The monument consists of a small circular area, roughly four metres across, defined first by a shallow internal fosse, which is simply a ditch, about 2.9 metres wide and 0.35 metres deep. Around that sits a low earthen bank, and beyond the bank a second, deeper fosse, this one 5.5 metres wide and 1.6 metres deep, gives the structure real presence in the landscape even now. A further outer bank completes the arrangement, though it has been breached in two places, at the north and again at the south-west, with gaps of four and 5.5 metres respectively. The southern arc of this outer bank has been truncated, most likely by repeated ploughing over the years, which has shaved down what would once have been a more pronounced ridge. It is a common story for monuments of this kind in tillage country, gradual attrition rather than sudden destruction, the monument shrinking by degrees with each turning of the soil.
