Christ Church in Llawryglyn was once the Catholic Church serving this region of the parish of Trefeglwys. It appears on the first Ordnance Survey map of Montgomeryshire, marked as Eglwys y Drindod-Sanctaidd; the Church of the Holy Trinity. As the congregation reduced the church fell into disuse, and it has since been redeveloped into two domestic dwellings.
The church was a long-wall entry type built in the gothic style. It comprised a continuous nave and chancel with off-centre tower, which has since been removed. The masonry building had arched fenestration, a slate roof, and stepped buttresses, while the belfry was of particular note for its carved wooden slats.
