Urban centres are regions where commerce returns and daily business is done. These areas of the city, which are frequented by people from all walks of life for trade or touristic purposes, are frequented by people who do their jobs. Bankalar Street in Karaköy has been the commercial centre of the city since the 19th century. The historical buildings were shaped according to the understanding of the period. The region, which used to be a trade centre in the past, has now become more touristic. The aesthetic application of graphic design elements in such areas, which have a very important place for the texture and identity of the city, is also critical for the image of the city. The visual identity of the city is formed and developed over a long period of time in ancient cities. It never takes its final shape. When it comes to the city, constant change is essential. The identity of the city is a whole with its architecture, culture and people molded in time. Both visual pollution and the non-aesthetic use of graphic design elements in historical areas, which are critical for the image and identity of the city, may damage the texture of the city, and their careful and skillful use will strengthen the texture of the city. In this study, the visual elements in the historical Bankalar (Voyvoda) Street in Karaköy region, which is of great importance for Istanbul, will be examined.
