This is St Cyriac's Church in Lacock in Wiltshire, more precisely the early 14th century north transept was was then extended in the 15th century to the church standing today.
This was one of those shots where to get enough of the impressive architecture of the ceiling into the frame without a resorting to a handheld pano, I had to shoot it at wide, upward angle, and then dramatically adjust it in post to straighten all the verticals. (If I don't all my 365 pals will torture me with WhatsApp comments on the straightness of my shot for the next week, something I would never do to them ;-) ).
