The bridge on the northern edge of the Ryecourt demesne in County Cork quietly does rather more, mixing three different arch forms in a single structure in a way that suggests either a pragmatic builder working around difficult ground, or a crossing that was modified and reinforced more than once over its lifetime. That combination of shapes, elliptical at the north end and segmental elsewhere, gives the bridge an asymmetry that rewards a second look.

The bridge spans just over six metres in width and carries four wide arches, each built with roughly cut voussoirs, the wedge-shaped stones that lock an arch together. The northernmost arch is elliptical, a flatter, more elongated curve than a true semicircle, while the remaining three are segmental, meaning they describe only a shallow arc rather than a full half-circle. All four have been underpinned at some point, a sign that the foundations needed strengthening, perhaps in response to the pressures of soft or waterlogged ground. Low pointed breakwaters project from the piers to divide the current and reduce erosion. On the southern face, a semicircular overflow arch provides a secondary channel, presumably to handle floodwater without stressing the main structure. The bridge sits on the northern boundary of the Ryecourt demesne, the country estate recorded nearby, and its scale suggests it was built to serve more than a farm track.
