Ringforts
In a pasture field at Mountaincommon in County Mayo, a roughly circular earthwork sits quietly on a slight rise, its outline softened by centuries of weathering and the slow accumulation of field clearance stones.
This is a rath, a type of ringfort built during the early medieval period, typically between the fifth and twelfth centuries, and used as an enclosed farmstead by a family of some local standing. What makes this particular example quietly interesting is not dramatic preservation but the opposite: the way its gradual erasure from the landscape can still be read, feature by feature, in the ground itself.
The rath measures approximately 30 metres north to south and 31 metres east to west, defined by a low inner bank of earth and stone, and reinforced along its southern to west-northwest arc by a fosse, a defensive ditch, and an outer bank beyond that. The fosse has silted up considerably over time and is partially choked with field debris, and the outer bank has been levelled along its eastern and southern stretch, though a faint undulation in the surface still betrays where it once ran. A gap of around three metres in the inner bank at the east-southeast is thought to mark the original entrance. Inside, the ground level is noticeably higher on the western half than the eastern, a subtle unevenness that suggests the site has its own internal history of use and modification. Hawthorn and blackthorn now colonise both enclosing banks, and the interior is scattered with hawthorn bushes growing up through the grass, a common pattern on undisturbed earthworks where thorny scrub is left to grow unchecked. What gives the site additional context is its neighbours: two further raths lie within a few hundred metres, one approximately 260 metres to the west-northwest and another around 145 metres to the east. This kind of clustering is not unusual in the Irish midlands and west, where early medieval communities often settled in loose groupings of related farmsteads rather than in nucleated villages.
