Well turkey had once a great empire and was a powerful nation, but unfortunately Atatürk ruined everything, it is now a shadow of its former self, best knows for kebabs, thats all.
Listen arab, i don't want insult you but wake up, you shall stop your fucking messages about Atatürk. This is sensitive subject that you are not suppose to talk here or anywhere. If you really wonder who is Atatürk and what he did, open some pages from history, then read until you learn something and see whether ruined or showed democracy to entire world. PS: As i read from your messages, you are not informed about these things since you're talking verry silly. So, I won't argue with you on Atatürk or Türkiye. If you don't know, please don't write maybe you mask your idiocy. I promise i keep it as a secret.
Hagia Sofia (mosque turned museum) is one of the most frequented landmarks in Istanbul. Definitely worth seeing.
