The original Llandinam English Presbyterian Church was built before 1800, rebuilt in 1823 and rebuilt again in 1873. The present chapel, dated 1873, was designed by architects Szlumper and Aldwinkle of Liverpool and built in the Gothic style with a long-wall entry plan, a schoolroom at the rear, flanking turrets and ogee headed windows with diamond glazing. Llandinam is now Grade 2 Listed as a well preserved and successfully designed chapel.
