Within the scope of the City Detectives project we carry out with the Koruncuk Foundation, our middle and high school students made an inspection trip to Bolluca-Arnavutköy in order to understand their relations with the city and their immediate surroundings from the perspective of the right to the city, to observe urban problems on site, and to understand the impact of the major projects carried out in recent years on the trace of Alibeyköy stream, one of the important streams that feeds Istanbul.
