The location of the geometric centre of the Earth depends on how you map the planet. One old calculation put it near Giza; another put it 1,000 km north of Giza, in modern day Turkey; and “Islamic scientists” (I don’t know who they are) put it near Mecca, of course.
Google maps agrees that it’s in Turkey: http://www.hurriyetdailynews.com/google-marks-turkeys-corum-as-center-of-the-earth-100514
As usual, there’s enough variation in the ways to map and measure the Earth that people can come up with their own favourite spots to be the geometric centre.
