Diyarbakır is rough. At first glance, it seems not a very welcoming city, actually it is the contrary. Lıfe in this city is hard for so many people. It is not advisable at all to walk alone during the night time, especially in the old quarter. Taking some precautions during the visit is advisable, just common sense. Don't hang around in dark areas; try not to look like
the typical tourist, etc.
