At Carrownamorrissy, a complex of rectangular fields survives as low, grassed-over stony banks, the kind of feature that is easy to walk across without quite registering what you are looking at. These are not the sweeping lazy-bed ridges of post-famine agriculture, nor the broad enclosures of later farming. They are small, measured, domestic, the largest reaching only about 28 metres by 18 metres, laid out across an area roughly 250 metres by 200 metres and concentrated to the north-east of a castle that still stands nearby.

What makes the site quietly arresting is its completeness as a landscape rather than a monument. Within the field boundaries sit the remains of several small rectangular houses, suggesting that this was once a functioning settlement, a place where people farmed their immediate surroundings and lived among the plots they worked. A possible enclosure has also been identified within the complex, though its precise function is unclear. The relationship between the fields and the adjacent castle hints at a organised rural economy, perhaps dependent on or associated with whoever controlled that tower, though the precise chronology of the settlement has not been firmly established. Field systems of this type, defined by low stone banks rather than earthen ditches, are a recurring feature of the Irish landscape, often representing the agricultural organisation of late medieval or early modern communities before larger-scale land clearances and consolidations reshaped the countryside.
