The grass-covered platform measures 34 metres from northwest to southeast and nearly 30 metres from northeast to southwest, creating a substantial rectangular space that would have once held buildings or served as a defended enclosure.

The site is defined by water-filled ditches or moats on all four sides, which vary in width from about 4.7 to 7.5 metres at the top, narrowing to between 2.2 and 4 metres at their base. These defensive features, though now quite shallow at 0.2 to 0.7 metres deep on the inside and up to 0.6 metres on the outside, would have been considerably deeper when first constructed. On the southwestern side, there’s an additional outer bank measuring 4.7 metres wide, though it now stands only 0.1 to 0.2 metres high.

Over time, the southwestern perimeter of the platform has been overlaid with a drystone wall and hedge running northwest to southeast, giving the entire complex maximum external dimensions of approximately 49 metres by 41.5 metres. These later additions likely date from when the site was incorporated into field boundaries, a common fate for many medieval earthworks across Ireland. The positioning near the river would have provided both a water source and potentially helped fill the defensive moats, whilst the location at the edge of the floodplain ensured the site remained dry during seasonal flooding.
