These are ring-ditches, a term for roughly circular enclosures defined by a fosse, or ditch, cut into the earth. They are associated in Irish and British archaeology with prehistoric funerary and ceremonial activity, sometimes the eroded remnants of burial mounds, sometimes standalone ritual enclosures. What makes this particular cluster quietly remarkable is that it was never found by a fieldwalker or an excavator; it was spotted through satellite imagery, the ancient and the modern in an unlikely collaboration.

The group consists of five small enclosures, each roughly ten metres in diameter, scattered across tillage land. They were identified and reported by Jean-Charles Caillère, who noticed the cropmarks on Apple Maps satellite imagery. Cropmarks form when buried ditches or banks affect the moisture and nutrients available to plants growing above them, causing subtle but visible differences in crop height and colour when viewed from altitude, especially in dry summers. The five ring-ditches are not evenly spaced. The two outermost examples in the group sit approximately 280 metres apart, while the two closest are only around 25 metres from one another. A fifth enclosure sits roughly in the centre of the group, lending the scatter a loose but discernible arrangement across the field.
