This sleepy and rather socially conservative area of Istanbul hosts a small but thriving Jewish community, the patriarchate of the Eastern Orthodox Church, and some of the most beautiful churches and Christian art in the world. Much of what’s most interesting to witness in Fener and Balat sits between the surviving ancient city walls of Constantinople and the serene shores of the Golden Horn. Despite the many splendid sights, historic attractions, stunning vistas, and warm Turkish welcome, the area remains largely unperturbed by the tourist trade that characterizes the atmosphere in nearby Sultanahmet and around the Grand Bazaar. Travelers that like to explore off the beaten track will reap big rewards for making the effort to visit this low-key part of town.
