Kudos to the son of David Ben Babae, who two-and-a-half years ago went to Tehran's Beheshtieh Jewish cemetery meticulously to document the gravestones. (Via Jewish +/- Irani , with thanks: Albert). Ben Babae Junior has now posted all his photographs on this website.
You will notice that some of the gravestones are broken up or in a state of disrepair while others are well tended.
The website makes a reference to 60 'Holocaust victims' buried at Beheshtieh. In fact these seem to have been Polish Jews en route to Palestine through Iran, or imprisoned in Tehran by the Russians, who died in a typhoid epidemic in 1942.
