around the city. We have made a significant change to the regional map on the second side of the sheet; in this edition, we provide a very detailed map of North-eastern Turkey, from the Greek and Bulgarian borders south past Cannakele and Edremit and east to Bolu in the scale 1:550.000. This enables the user to focus on realistic driving/bussing times to reach destinations within a reasonable distance of Istanbul. Both maps combine to portray a fascinating city and region.
