Bunhill Fields Burial Ground: His cap betrays his employer: the City of London. He is one of the groundskeepers at Bunhill Fields, but he also doubles as 'attendant with key.' Want to see the grave of the father of Bayesian statistics or the mother of John Wesley? He will unlock the gate and take you there. In other words: Conform to the rules! Non-conformists not welcome. Or it might just be a conservation measure. On the map below, all graves along the winding white paths are closed to the public unless you find an attendant.
