I’m surprised the authorities would allow anything pre-islamic. Unless they assume everything to have been islamic even before the so-called prophet arrived to give muslims over to such madness, and 1400 years of inbreeding.
Turkey is full of pre-Islamic sites... including the world’s oldest sites Göbekli Tepe which dates back to the 10th millenium BC and Çatalhöyük which dates to 7000 BC. Turkey is not your typical Islamic country... even with Erdogan’s changes, it still reveres the modern western perspective Atatürk ushered in.
