The earthwork consists of a substantial artificial mound, roughly circular in shape with a flattened summit that measures approximately 21 metres from northwest to southeast and 18 metres from northeast to southwest. The entire structure rises 3.5 metres high, with the base spanning an impressive 36 metres across at its widest point. Today, the grass-covered summit is dotted with trees, offering a peaceful contrast to its original defensive purpose.

The motte is encircled by a shallow fosse, or defensive ditch, which would have provided an additional layer of protection for the wooden castle structure that once crowned the summit. This ditch, measuring 6 to 7 metres in width at the top and reaching depths of 30 to 40 centimetres externally, is still visible today, though centuries of weathering have softened its edges. The name Moat Town itself reflects the enduring presence of this medieval fortification in the local landscape and memory.

These mottes were typically constructed by the Anglo-Normans following their arrival in Ireland in the late 12th century, serving as both military strongholds and administrative centres for newly conquered territories. The wooden palisade and tower that would have originally topped this mound have long since disappeared, leaving only the earthwork to tell its story. Archaeological surveys conducted for the County Meath inventory have helped preserve knowledge of this site, with the most recent updates in 2016 ensuring that our understanding of this medieval monument continues to evolve with new research.
