Traditional Grave of John Calvin

From Wikipedia:

 Calvin died on 27 May 1564 aged 54. At first his body lay in state, but since so many people came to see it, the reformers were afraid that they would be accused of fostering a new saint’s cult. On the following day, he was buried in an unmarked grave in the Cimetière des Rois.^[81] The exact location of the grave is unknown; a stone was added in the 19th century to mark a grave traditionally thought to be Calvin’s.^[82]
