Visible as a cropmark in aerial photographs, this rectangular enclosure at Graheeroge measures approximately 40 metres on each side, forming an almost perfect square. The site’s boundaries are defined by what appears to be an ancient fosse or moat system, a defensive feature that would have once surrounded whatever structures stood within.

This type of fortified site, known as a moated site, was particularly common in medieval Ireland, typically dating from the 13th to 14th centuries. These enclosures often marked the homes of Anglo-Norman settlers or prosperous Irish families who adopted Norman building practices. The moat would have served both defensive and symbolic purposes; whilst providing protection from raids and cattle theft, it also demonstrated the status and wealth of its inhabitants.

Today, the site at Graheeroge exists primarily as subtle variations in crop growth patterns, with the filled-in moat affecting soil moisture and fertility differently than the surrounding land. These cropmarks are best observed during dry spells or at certain stages of crop growth, when the ancient features become temporarily visible from the air. The site forms part of County Wexford’s rich archaeological landscape, documented in the Archaeological Inventory of County Wexford and continuing to provide insights into medieval settlement patterns in southeast Ireland.
