The Sub-rectangular Enclosure at H107 403 is a uncertain enclosure located in County Fermanagh, Northern Ireland. The site comprises an earthwork of sub-rectangular form, its precise chronology and function remaining unclear from the physical evidence alone. Such enclosures are found throughout the Irish landscape, their origins spanning from prehistoric through to medieval periods. The underlying bedrock here comprises rocks of the Tyrone Group, a Visean-age sequence of limestone, mudstone, sandstone and siltstone with subordinate chert, coal and conglomerate, which would have influenced both the site's natural drainage and the character of available building stone.
The enclosure is protected by the Historic Environment Division under reference 10828. The monument's location within Fermanagh's distinctive karst terrain, shaped by its soluble limestone geology, places it within a landscape rich in archaeological remains. Fermanagh's abundance of water bodies and natural harbours has long supported settlement and activity.
Without supporting finds or excavation, the precise function of this enclosure—whether domestic, agricultural, ritual or defensive—remains to be established. The site contributes to the broader archaeological record of Fermanagh and demonstrates the varied settlement patterns evident across the region.
