Before he became famous, British novelist Thomas Hardy (1840-1928) worked as an architect. One of his more unpleasant projects was the relocation of an old graveyard to make way for the expansion of London. He arranged for the relocation of the bodies, but without their accompanying headstones. These he arranged in a circle around an ash tree in the St Pancras Churchyard. You can view more pictures of this tree, popularly known as the Hardy Tree, at the link.
