The main church, cruciform in the “transitional style from Norman to Early English with a clear French influence”, is an ornate structure built of local granite with Caen stone dressings, with a high altar with solid round pillars and the nave supporting towering arches. It became an archetype model for six other churches built by the same architect. The original six Victorian bells were removed during the German invasion; four were taken to Cherbourg to be melted for making munitions, and two were found in Alderney. All six bells were recast by Taylor's of Loughborough in 1953.
