The original chapel was built in 1858 to the design of R. Moffat Smith of Manchester. It was rebuilt or modified in 1885 to the design of Owen Edwards of Rhyl. The present chapel is built in stone, in the Gothic style with asymmetrical facade, having a short saddle-backed tower between the chapel and lecture hall fronts. It is listed Grade 2, and was still in use in 1994.
