The Presbyterian church in Castlebellingham was built in 1840 according to the date inscribed on the recessed shield above the front doors. The church is a freestanding, single storey building and has rendered walls and painted timber windows with diamond pattern cast-iron light panes.

According to Ireland’s National Inventory of Architectural Heritage

“The understated simplicity of this church contributes to its character. It retains some interesting architectural details such as Y-traceried windows with cast-iron lattices and tooled stone window and door surrounds.”

The church ceased to be a place of worship in the 1990s after the congregation moved to a more centralised location in Dundalk.
