I walked near Taksim and arrived in a district where the houses were almost falling apart. Then a fire broke out. It was obvious the city was "upgrading" this district, which as usual implied that the current occupants had to move. They told me they did not want to do so.
Last time I read about a district nearby, with similar conditions, was that a court had decided the whole procedure of evicting people had been illegal. I also noticed when passing that the promised bright new apartments somehow had not arrived.
