Büyükada has banned the private car for generations — the loudest sounds on its lanes are bicycle bells and, until recently, hooves. The largest of the Princes' Islands, it grew as a summer refuge for Istanbul's Greek, Armenian, Jewish and Levantine families, who raised extravagant timber mansions among the pines. Two wooded hills crown it: one holds the abandoned Prinkipo orphanage, once the largest wooden building in Europe; the other lifts the whitewashed monastery of Aya Yorgi. Leon Trotsky passed four exiled years here, writing in a rented house above the shore.
Today you step off the ferry into a town of faded belle-époque facades, then head uphill as the streets surrender to shade, resin and glimpses of sea. On the two feast days of Saint George the track to Aya Yorgi fills with tens of thousands of pilgrims, most of them Muslim women. An outbreak of horse disease closed the phaeton stands in December 2019, and a month later the city bought out all 277 carriage licences. Battery minibuses do the climbing now. The grand houses grow quiet each winter, then every spring the island fills again with day-trippers, the ring of bicycles, and the smell of salt.
