Oooh, Alexander’s tomb, a good one! I’ve seen (but couldn’t find online just now) a pic of a Ptolemaic-era structure (maybe a tomb) which is a miniature version of the Pharos. :’)
I think some German archeologist claimed some time ago that she had found the site of the oasis where he was supposed to be buried in the Western desert of Egypt. I believe there was a FR post on it.
Of course it is a long way from finding an oasis to finding a tomb.
I’ve always thought it was a strange choice for his burial and perhaps a ruse by his loyal followers to send future tomb robbers out into the desert to search futilely until they died.
