The Parish Church met in a neo-Gothic building next to river, completed in 1846, and had a separate facility, the Mission Hall, on the other side of the river, built in 1885.

The Mission Hall was used as Red Cross Hospital during the Great War, opening in … 1914 and run by Lady Ewart.

The minister was Rev James Buchanan, born in Airdrie, Lanarkshire to a coal pithead labourer. He was appointed in 1879 at age 35 and was originally an apprentice law clerk before joining the ministry.

The church had a fine Willis pipe organ and a paid organist and choirmaster, Charles Metcalfe. Born in Carlisle, he was a professor of music in London before moving to Langholm in 1893, the same year as the installation of the organ. His father William was an organist for Trinity Church, Carlisle, and had musical associations with Langholm.

A church memorial lists 58 names of those in the congregation who lost their lives in the Great War.
