A Bronze Age barrow cemetery comprising 13 monuments, only one still extant as an earthwork. The remainder have been recorded from air photographs. The extant mound, Grinsell's Avebury 19b, is extant as an oval turf-covered mound measuring circa 26 metres by 21 metres across and up to 1.3 metres high. The oval shape appears to be partly caused by deposition of spoil from an extensive central mutilation, presumably an unrecorded antiquarian excavation. In 1992, it was noted that the mound had been dug into once more, and was in need of repair. The spoil from this episode contained a flat, rivetted copper alloy dagger, plus Bronze Age potsherds, struck flint, and cremated bone. See associated monument records for other barrows, ring ditches and cropmarks in this group.
