St. Chad's Church has an Anglo-Saxon west tower, not tall. There are twin bell-openings with mid-wall shaft (much restored - see the Nattes drawing). {1} Trollope suggests that the tower was of an early Norman date. His description: nothing relieves its plain simplicity but the belfry lights, now partly concealed by modern adjuncts, and a single simple string marking off its upper stage. {4} The square, unbuttressed tower is Anglo-Saxon, of carefully coursed small rubble with larger blocks of rubble for the window jambs and the side-alternate quoins. The tower is of two stages, separated only by a plain, square string-course. The lower stage stands on a plain square plinth and has no surviving features of definitely Anglo-Saxon character. The upper stage originally had four round-headed double belfry windows, the one on the west face has been blocked and largely cut away. The three surviving windows are single-splayed with mid-wall shafts of plain circular cylinders and simple conical capitals which are changed into a square plan at the top by the addition of little knobs at each of the four angles. No Anglo-Saxon feature has survived internally. {5} A church at Harpswell is mentioned in the Domesday book. {6}
