These are ring-ditches, a term used to describe circular or near-circular ditched enclosures that typically survive only as cropmarks, where buried features cause the vegetation above them to ripen at a slightly different rate, creating patterns that become visible under the right light and conditions. They leave no earthwork, no mound, nothing to stub a boot on.

The three ring-ditches at Toberburr are arranged in a roughly north-south line within the field, close to its eastern boundary, and lie approximately 452 metres west-southwest of a separate ring-ditch recorded nearby. The northernmost of the group, designated Ring-ditch 1, is circular in plan with an external diameter of around 8 metres and a ditch roughly 1 metre wide. Notably, there is no evidence of an entrance gap through the ditch, which distinguishes it from enclosures designed for habitation or regular access and may point toward a funerary or ritual function, as ring-ditches of this type are frequently associated with Bronze Age burial. The grouping of three in a linear arrangement suggests a deliberate spatial relationship between them, though the precise date and function of the site have not been established through excavation. The records were compiled by Tom Condit and uploaded to the national database in April 2021, drawing on Google Earth imagery captured in June 2018.

Because the features exist only as cropmarks, there is nothing physically to see at ground level, and the field is agricultural land rather than a managed heritage site. The imagery from Google Earth remains the most accessible way to observe the marks directly, using the June 2018 date as a reference point when the cropmarks were clearly visible. Anyone with an interest in aerial archaeology or the wider prehistoric landscape of the Fingal area will find that scanning available satellite and aerial archives around the summer months, when cereal crops are maturing, gives the best chance of picking out such features across the region.
