Considered to be the finest in Middlesex, the South Doorway is not only one of the church’s most treasured architectural possessions, but is also an excellent specimen of Norman craftsmanship.

Rounded columns support an arch which is decorated with the distinctive Chevron motif and a humorous row of cat heads.  Protecting it is an oak Porch added in the Elizabethan period.  Once thought to have stood over a lych gate, the visitor will notice that its width does not quite correspond with that of the doorway.

Most conspicuous of the external features is the West Tower, a structure of three storeys with a castellated parapet and North east turret surmounted by a small Eighteenth century cupola.  This houses the clock bell and is capped by a golden ball and weather vane.  Directly above the West Door, which has a typically late medieval hood mould, is a handsome Fifteenth century window of three lights.  High above, on the same face of the Tower, is a smaller two light belfry window of the same period.
