Büyükada (Greek: Πρίγκηπος or Πρίγκιπος, rendered Prinkipos or Prinkipo), meaning "Big Island" in Turkish, is the largest of the Princes' Islands in the Sea of Marmara, near Istanbul, with an area of about 2 square miles (5 square kilometres). It is officially a neighbourhood in the Adalar (Islands) district of Istanbul Province, Turkey. During the first half of the 20th century, the island was popular with prosperous Greeks, Jews and Armenians as a refuge from the summer heat of Istanbul. Nowadays the island is almost as solidly Turkish as any suburb of mainland Istanbul. Historically, many residents of Büyükada were fishermen. However, by the late 2010s tourism to Büyükada swelled enormously as it became a favourite day-trip destination for visitors from greenery-starved Arab countries in particular. The surge in tourism was a major factor in bringing to an end the tradition of using phaetons as the only transport on the island in 2020. Visitors have been writing about Büyükada since the Turkish travel writer Evliya Çelebi recorded in his Seyahatname (Book of Travels) that there were 200 Greek houses on the island in 1640 and that it was ringed with dalyan fishermen. In 1884 the French historian Gustave Schlumberger published Les Iles des Princes, describing his visit to the archipelago. Ernest Mamboury recorded the sites of the island in his Les Iles des Princes, published in 1943 and Jak Deleon updated his work in 2003 in his Büyükada: A Guide to the Monuments. After leaving the island in 1933 Trotsky wrote an essay called Farewell tp Prinkipo. In 1997 Çelik Gülersoy, who had worked to restore some of the island's buildings, published Büyükada Dün (Büyükada Yesterday). In 2007 John Freely's The Princes' Islands exhaustively listed the historic mansions on the island. In 2009 the poet and translator Joachim Sartorius published an exquisite short travelogue called The Princes' Islands: Istanbul's Archipelago which mainly focused on Büyükada. The island is accessible by Şehir Hatları ferries from Eminönü and Kabataş on the European side of Istanbul and from Kadıköy and Bostancı on the Asian side of the city.
