C4622 : Culmore Church of IrelandCulmore Parish Church of Ireland is dedicated to the Holy Trinity and the building was completed in 1867 to the design of John Guy Ferguson. Alistair Rowan's 1979 Pevsner guide to North West Ulster describes it as "a miniature cruciform church in rubble schist with sandstone dressings, three-bay nave and two-bay chancel. A big Decorated west window and an offset north porch with octagonal belfry and stone spire above."
He notes that the ruinous gable wall in the churchyard is the remnant of a 17th-century garrison church that was demolished by James II in 1689.
