In Turkey, you can find the most surprising things. Here is a photo of the ancient city wall and tower of Nicomedia in northwest Turkey. The Greeks built it about 2000 years ago, and it still stands beside a modern restaurant at a hilltop park. The restaurant made use of the tower’s interior by putting a door over it and using it for storage, but I like to think of it as a mysterious cave into earth’s distant past, full of shadows, carved stone, and spider webs. Perhaps it also hides undiscovered treasure like a gold ring lost by a visiting king long ago. His body has since passed to dust and his name forgotten, but the gold ring may still be found by a curious restaurant diner in our modern world.
