At Clorhane in County Limerick, a pair of trapezoidal enclosures sit in the landscape in a shape that ordinary agricultural use rarely produces. Most field boundaries follow convenience, topography, or inheritance; a trapezoid, with its deliberate angular geometry, tends to suggest something older and more intentional beneath the surface.

The site consists of two trapezoidal enclosures, and at least one of them has a documented cartographic history worth noting. The smaller of the two appears to correspond to a trapezoid marked on all three editions of the Ordnance Survey maps of the area, meaning it was recorded consistently across the nineteenth and early twentieth centuries without anyone apparently deciding what it was or assigning it a formal designation. That kind of quiet persistence on maps, noted but unexplained, is often a reliable sign that something genuinely old is involved. The site was identified and compiled by Matt Kelleher, drawing on information supplied by Stuart Elder, and was uploaded in August 2023.

The more clearly visible of the two enclosures can be located using the coordinates 52.596244, -8.793153, and is discernible on current satellite imagery, which is often the most practical first approach to a site like this before committing to a ground visit. Field systems of this kind can be difficult to read at ground level, where the boundaries may present as nothing more than low earthen banks or subtle changes in vegetation. Comparing the satellite view against the relevant OS map editions before visiting will help orientate what you are looking at once on the ground. Access arrangements in rural Limerick vary, and the site sits on private farmland, so the usual courtesies apply.
