The South Porch, which was constructed in the early 16th century, originally consisted of timber framing on dwarf rubble walls. The openings between the timber uprights were filled in later.

On either side of the doorway is a design in flint – a Cross on the eastern wall (left) and and an upside-down Fish on the western one (right).

There are also sundials scratched into the walls on either side of the door. These consist of small circles with lines radiating from a central hole that would have held a peg or pin. They probably predate the building of the porch.
