Bunhill Cemetery in London is unusual in that it is on unconsecrated ground. For this reason it was popular with the religious dissidents of its day, in particular Quakers, atheists, and agnostics. I'd recommend it as a nice quiet spot to visit, if you're in the vicinity.

This is what mainly drew me to Bunhill: William Blake's gravestone. Most of the graves are in fenced off areas which you can't (legitimately) get to, and for a while I feared I might not find this, but gladly it (and Defoe's & Bunyan's) are thoughtfully outside the exclusion zones.

The flowers are bluebells, in a jam jar - sweet, huh? I wonder who left them there... I fiddled around with colouring them in using The Gimp but the results weren't great so I left it.

Here are some of Blake's paintings.
