Last week, as Mike Iliff was in London, I reciprocated his tour of Llangeitho with one of Bunhill Fields and the Wesley Museum (hence the recent list here). Besides the godly men Bunhill Fields is the final resing place also of the writer Daniel Defoe (who did come to faith later in life, I believe. Robinson Crusoe is worth reading for the evangelical content alone) and poet and painter William Blake (a Swedenborgian by persuasion). For more on the dead of Bunhill Fields, see Alfred W Light's tome, accessible here. Across the road from Bunhill Fields is the Wesley Chapel and the house in which he latterly lived. It was good to see that again. There is a little museum in the basement of the chapel. Wesley is buried behind the chapel. Both places are free to enter, the nearest tubes being Moorgate and Old Street. More here and here.
