I initially thought that it was St Mary's Little Chart, but the pictures didn't match. Then I remembered that there was another ruined St Mary's around Ashford, and a quick search got the match on the grille covering the doorway.
Now up until now I have always used photos that I have taken or scanned from others in my possesion. I have virtually run out without spending a long time ferreting about in boxes. So.. here is my first attempt at a screenshot from the Internet. It was a subject that I noted many moons ago, but have not had the chance to get up close with a camera.
Hope it comes out OK
