Was there a South Aisle?
Removing the interior render has shown up a couple of arches now filled in that suggest there may have been another aisle to the church in the past.
First some Quoin stones on the exterior
And here is the inside (higher up). This picture also shows a Weald stone and 2 Core stones surrounding some fill that would have been an old Putlock (ie scaffolding) hole
Another Arch being revealed at the East end of the Nave's South wall;
And another from outside - signs of an entrance now part hidden by the porch;
