That has been a rule for a long time, way before Erdoğan. When I was visiting Turkey as a child about 18 years ago, there were signs all over the airport saying that it’s illegal to remove artifacts, stones, etc. from the country. The signs mentioned that the punishments can be high fines and even go up to imprisonment.
Sometimes reading helps…
Yo momma so stupid she tried to steal rocks from Turkey and got arrested
A regular stone??? Fuck Erdogang
Pebble in your shoe? Straight to jail.
We have the best tourists because of Law! 😂
It was s stone with a carved pattern, they argued it has historical value. She took 3 stones iirc.
The article – which may or may not be accurate – seems to say that there is a prohibition on stones in general, not just carved stones:
However, under Turkish law it is forbidden to just take stones out of the country with you.
Could just be unclear phrasing, of course.
