TAKE the TURKEY (TURKIYE) TOUR:
THE SUNKEN CITY
Little remains of the old city, near Yalova, which according to local tradition was destroyed by an earthquake
about 300 BC.  Short-timers (those who were near the end of their two-year sentence, as they viewed their
military tour in Turkey) talked with excitement about the "Sunken City."  Some had even dived there, but the
water was murky and dark with low visibility.  

The old domed ruins of a building (see picture above) stood about midway between Karamursel Air Station and
the town of Yalova, which was about twenty miles to the west.  The familiar landmark was at a wide spot in the
narrow dirt road near the shore of the Bay of Iznik (Bay of Nicomedia and the Astacus Sinus in ancient times).  
Marble columns lying in the water indicate that part of the city may be under what is now the bay.  

A map of the ancient world in the 7th century B.C. shows an Ionic settlement in this area.  Ionians spread from
the western shore of Asia Minor as far as the Black Sea (The Euxine or the Pontus Euxinus  in ancient times).  
The Ionians were a confederation of the twelve cities: (1.)  Miletus (2.)  Myrus, (3.)  Priene (4.)  Ephesus  (5.)
Colophon  (6.)  Lebedus  (7.)  Teos (8.)  Erthrae (9.) Clazomenae (10.)  Phocaea  (11.)  Samos (island)  (12.)  
Chios.  The Ionians were subdued by Croesus, King of Lydia, in the middle of the 6th century and after him
were under the Persian Empire, and then the Greeks under Alexander the Great.

On the map above, note the location of the sunken city in relation to old
Constantinople (now Istanbul, Turkey), which is about forty miles northwest.  The
Roman emperor Constantine was visiting the hot baths at Helenopolis  shortly before
his death.  He was traveling back to Constantinople along this road. Constantine died
on the 22rd of May, 337 A.D., at Ancyrona near Nicomedia.  His body was placed in a
golden coffin and taken back to Constantinople for burial.
