Izmir was a city in western Turkey.
In 2008, a call centre owned by Ephraim Salt where Zeynep worked was located in Izmir. She said Izmir has a river "that's so poisonous you don't hang your washing out when the wind changes". Her office had a view of an illegal sand quarry where people crashed cars. The SkyPuncher spaceship crashed into that quarry on its maiden voyage. (AUDIO: Fall to Earth)
Izmir was vanquished by the Master during the Year That Never Was, and a statue of him was erected outside of it. Martha Jones flew over Izmir in a Chinook owned by the Turkish Air Force. (PROSE: The Story of Martha)
