In the frame of these identified criteria, Nisantasi example is examined in the context of lighting pollution. Important streets and lanes and important historical and religious structures that gained a seat in public memory are identified. Designing criteria of the lighting tools existing in these identified areas and their suitability according to their spot are evaluated and measuring their illuminance sufficiency, the issues which are detected as light pollution are stated. In conclusion, the studies done in our country are cited and the issues that are to be done to prevent light pollution are introduced as a suggestion
