The pointed arch between the nave & tower, & the tower & spire are of the 13th century. A peal of six bells, of various dates from 1753 onwards, hangs in the tower. The bells were recast & retuned in 1973. Tower & spire can be seen over wide distances by land & sea. Up to 1853 the spire was covered with slates. Since then, it has, like the tower, needed to be made weather tight with a skin of cement. The local stone, of which the Church is built, is unfortunately, very porous. The 15th century reconstruction of the church included lengthening the North & South aisles to form two large Chapels on either side of the Chancel from which they are separated by oak parclose screens. An oak Rood Screen was erected at the West end of the Chancel & its aisles, & a staircase turret built against the wall of the South aisle to provide access from an upper doorway to the Rood Loft, or Gallery, running the whole length of the top of the screen.
