Three ring-ditches, arranged in a rough line running north to south, are invisible to anyone walking across the field but show up clearly as cropmarks, the subtle colour and growth differences in crops or grass that betray buried features beneath the soil. It is a peculiar kind of archaeology: the site exists, in practical terms, as an image on a satellite photograph rather than as anything you could point to on the ground.

A ring-ditch is the filled-in remains of a circular ditch, most commonly associated with prehistoric burial monuments. They are often what survives when the original earthwork above ground has been completely levelled by centuries of ploughing. The southernmost of this group of three, designated Ring-ditch 3, is circular in plan with an external diameter of approximately 11.1 metres and a ditch roughly one metre wide. Notably, there is no evidence of an entrance gap through the ditch, which distinguishes it from some comparable monuments where a deliberate break was left in the circuit. The group sits roughly 450 metres west-south-west of a separate ring-ditch already recorded in the area, suggesting this part of north County Dublin was, at some point in the distant past, a place of some significance. The cropmarks were identified and recorded from Google Earth imagery captured on 24 June 2018, and the site was compiled by Tom Condit and uploaded to the record in April 2021.

Because the features here are subsurface, there is nothing to see at ground level; the field shows no visible earthworks. The best view remains a satellite one, and the Google Earth imagery from the summer of 2018 is worth consulting before any visit to understand the layout. Cropmarks tend to be most pronounced during dry summers, when differential moisture retention in the soil causes buried ditches and pits to express themselves in the growth above. The site lies close to the eastern boundary of its field, and the wider Toberburr area is accessible by road from Swords. Anyone with a serious interest in the site would do well to consult the National Monuments Service record, which holds the precise coordinates alongside the compiled notes.
