Headstones and tree roots create art.
When the Midland Railways planned to build their new railway line, in the area now known as Kings Cross and St Pancras, they had to figure what to do with the bones and gravestones in the large burial grounds surrounding the historic church.
This rather unenviable task fell to Thomas Hardy. He stacked some headstones around this ash tree, meaning to get back to them later, and never did. Probably because he rushed off to help Dickens write a tale of two cities. Time has seen the stones and the tree, known as the Hardy tree, meld together.
