I looked up this one on Wikipedia because my old pastor [will be 97 next month] many years ago visited one of those old cities in modern Turkey, Smyrna, now known as Izmir.I looked at the history of the 7 churches and they were all in Asia but each came and went in different periods of time....and none of them exist today...

Izmir, is a metropolitan city in the western extremity of Anatolia. It is the third most populous city in Turkey, after Istanbul and Ankara.
İzmir has more than 3,000 years of recorded urban history. In classical antiquity, the city was known as Smyrna, a name which remained in use in English and various other languages until around 1930 when government efforts led the original Greek name to be gradually phased out internationally in favor of its Turkish counterpart Izmir.
Years ago he told me about that visit but I recall little of it now. I will check with him again to have him recite the story to me again.
