Shrine

Man Ata. Little seems to be known about the inhabitant of this grave, now a shrine, attributed with being a protector of travellers. He was a Zoroastrian teacher or priest, from before the 10th century, when Islam came to Mangistau.

We have no idea what all the scripts are. But the last one had me most intrigued.

The majority of vehicles seemed to stop on the way past, with the occupants spending a few minutes in prayer and meditation at Man Ata's grave.
