According to their website, this St Mary's has been used in television shows; I don't think I've seen it though. [Poldark is not a suitable show for an impressionable bear, Big Ted!].
The church is down a long narrow road and is quite small and a bit overgrown. But it was open. There were these cross-shaped windows in the porch and Uncle Les took this clever photo of me through both of them at once. You can only just see me though!
