We also read the article and so today set off with our residence book in hand to the Fethiye Museum. Two smiling ladies greeted us on reception and when I asked to buy the Muzekart, they said it was only for Turkish citizens. I asked that they please check as I understood that the rules have changed, they said that the card application paperwork they have clearly states Turkish Citizens only and so refused our request.
The museum was interesting and well worth the 3 TL entrance fee.
