The building at Knockanemore, sitting at a crossroads in the village of Ovens in County Cork, was described as early as 1837 by the topographer Samuel Lewis as a "handsome edifice of hewn limestone, in the mixed Gothic and Grecian styles of architecture." That combination, sometimes called Gothick or Commissioner's Gothic in its various Irish incarnations, was not uncommon in early nineteenth-century church building, but the Ovens example carries the hybrid with some care: round-headed windows, a classical string course running along the exterior walls linking the window surrounds, and pedimented gables each pierced by a blind oculus, a sealed circular opening used here purely for visual effect rather than to admit light.

The church was erected in 1835 and is cruciform in plan, meaning it has the shape of a cross, with the main nave running east to west and a chancel at the western end rather than the more conventional eastern position. Inside, a flat plaster ceiling spans the nave, and wooden galleries were installed in both transept arms as well as at the eastern end, suggesting a congregation that needed the space. A small bellcote sits atop the east gable. The interior once contained a fine classical reredos, the decorative screen behind the altar, noted as being very closely related to one surviving at Grenagh, a few miles to the north. Both presumably came from the same workshop or pattern. The Knockanemore reredos did not survive a remodelling of the interior carried out in the mid-1980s, which leaves Grenagh as the better place to see what was lost here.
