Following the founding of the Turkish Republic in the 1920s, larger and larger buildings were built along wide avenues such as Halaskargazi Caddesi, the main road that runs through the middle of Şişli, with its little arcades of shops below tall buildings of apartments and offices. In the republican era, the area was still the residence of the middle-class, as well as traders there were now writers and poets and Şişli acquired theatres, cafes and other cultural amenities. The Hilton Istanbul Bosphorus was built here in the 1950s and many others followed.
