The feature, formed from glacial gravel deposits, stretches approximately 220 metres from northwest to southeast and 170 metres from northeast to southwest. At its southeastern end, visitors will find a level summit area measuring roughly 50 by 40 metres, though today the entire site is covered with a plantation of coniferous trees.

This imposing earthwork may have played a role in the medieval history of the area, with archaeological evidence suggesting possible connections to the medieval borough of Mulsoe’s Court. The hillock’s strategic position and distinctive shape would have made it an ideal location for defensive purposes or as a statement of authority in the medieval landscape. Its steep sides and elevated position would have provided excellent views across the surrounding countryside, making it both defensible and symbolically important.

The site forms part of the rich archaeological heritage documented in the Archaeological Inventory of County Wicklow, first published in 1997. Located within the historic Powerscourt Demesne, this moat represents just one element of a complex medieval landscape that once dominated this part of Wicklow. While the conifer plantation now obscures much of the original form, the underlying earthwork remains an impressive testament to medieval engineering and landscape modification in Ireland.
