Near the Beyazit mosque and the entrance to the Covered Bazar is the Sahaflar market, where the secondhand book sellers have their shops. It is on the spot where in Byzantine times was the Chartoprateia, book and paper market. Later the turban-makers and metal engravers took over (Hakkaklar market, after the Turkish name for the latter). At the beginning of the 18th century the book sellers moved here from inside the Covered Bazaar. Great place if you like books (or cats: many cats seem to have found a good home here).
