An Anglican church was first constructed at Abercarn by Augusta Hall where Welsh speaking Anglicans of the area could hold services. This building remained the property of the Halls. A decade or so after the church was built, the vicar asked permission to hold one service a month in English for the increasing number of outsiders coming to work in the mines and iron works in the valley. The Halls (by then Lord and Lady Llanover) refused and Anglicans were excluded in favour of Presbyterians. As a result another church was built for the Anglicans about 10 years later in 1890: a corrugated iron building which became the Parish Church of the new Parish of Abercarn. It remained as such until the new St Luke's was built and consecrated in 1926 (see NPRN 13129).
The earlier St Luke's church was located on the west side of Bridge Street, on its old alignment, and next to the Tinplate Works. The building portrayed on the Ordnance Survey second-edition 25-inch plan shows a simple rectangular box, aligned north-west by south-east, with what appears to be a porch on the gable south-east end. The building may have survived into the post-War period as it is shown (unannotated) on the OS fourth-edition six-inch plan. The entire area has since been redeveloped with a re-alignment of Bridge Street.
