worth matravers church, dorset

early c12 church with figurative corbel table, the porch prob.c18., the c12 chancel much rebuilt in the c13. I have a problem with seeing the triangular headed doorway as the entrance to a dec. transept though; they'd have had to block the c12 and c13 windows in the wall for the roof, and why would the c14 not cut a big arch and let some light in? it doesn't make sense. internally, it looks like it could be c13, without the original head, but it would only have suited a very small chapel indeed.
