Located about 100 metres southeast of what may be an ancient rath, this defensive earthwork sits at 743 feet above sea level in the townlands of Boherkill and Guidenstown North. The site consists of an almost perfectly square enclosure measuring 60 metres from northeast to southwest and 58 metres from northwest to southeast, defined by substantial earthen banks that have become cloaked in grass and thorny vegetation over time.

The defensive features of this moated site are particularly impressive. The surrounding bank, constructed from earth and stone, rises to 2.2 metres on the exterior and 1.7 metres on the interior, with a width of about 2 metres. Beyond this formidable barrier lies a broad outer fosse, or defensive ditch, that extends 6 to 7 metres wide and plunges 1.5 metres deep. The only break in these defences is a single entrance gap, 2.8 metres wide, positioned halfway along the southwestern side; a strategic placement that would have allowed the site’s inhabitants to control access whilst maintaining their defensive advantage.

Though the site has become significantly overgrown with vegetation, its preservation is remarkable enough that it was granted official protection through a Preservation Order in 2002. This medieval fortification represents the kind of moated site that wealthy Anglo-Norman settlers often constructed in Ireland during the 13th and 14th centuries, serving both as defended homesteads and symbols of authority in the landscape. Today, whilst nature has reclaimed much of the site, the earthworks remain clearly visible, offering visitors a tangible connection to Ireland’s complex medieval past.
