Enclosures
In a field in Newdown, County Westmeath, there is an ancient enclosure that nobody has yet excavated, touched, or even walked around in any official capacity.
It exists, for now, purely as a shadow in the grass. The site is a bivallate enclosure, meaning it was originally defined by two concentric circular banks or ditches rather than one, and it shows up as a cropmark on aerial imagery. Cropmarks form when buried earthworks affect how plants grow above them; over a filled-in ditch, soil tends to be deeper and moister, so crops grow taller and greener, while over a buried bank the reverse is true. From ground level there may be nothing visible at all, but from the air the underlying geometry becomes legible.
The enclosure measures approximately 50 metres in diameter at its inner circuit, with an overall external diameter of around 64 metres. That overall footprint is substantial, comfortably within the size range associated with high-status early medieval ringforts, though without excavation any such dating remains speculative. The site came to attention through Google Earth aerial imagery photographed on 2 July 2018, and was subsequently compiled by Caimin O'Brien on the basis of details provided by Edward O'Riordan. It is the kind of discovery that satellite imagery has made increasingly possible across Ireland in recent decades, revealing enclosures, field systems, and other features that centuries of farming have flattened but not entirely erased.
