I work in Battersea and sometimes go for a walk along the Thames there at lunchtime. It’s not the most picturesque stretch of the river, but there is a nice little church there with a friendly graveyard; by which I mean that it has benches for people to sit upon and contemplate their mortality.
A little research shows there has been a church on the site since around 800AD, that William Blake was married there, and that J.M.W. Turner used to paint scenes of the river from the vestry window.
I might summon up the courage to actually set foot inside one day and explore further.
