Two of the formerly three traceried windows in the south wall of the chapel remain in part and can be seen on the outside.  They were blocked up in the mid 16th century and in the middle one was inserted a small doorway with a brick arched head, later disused probably when the 17th century chimney stack was built.  The double buttress at the south-west angle of the chapel remains.   Much of the walling hereabouts has been rebuilt, no doubt in Elizabethan times.
