Halki Theological School Gardens

The Halki seminary, formally the Theological School of Halki (Greek: Θεολογική Σχολή Χάλκης and Turkish: Ortodoks Ruhban Okulu), was founded on 1 October 1844 on the island of Halki (Turkish: Heybeliada), the second-largest of the Princes' Islands in the Sea of Marmara. It was the main school of theology of the Eastern Orthodox Church's Ecumenical Patriarchate of Constantinople until the Turkish parliament enacted a law banning private higher education institutions in 1971. The theological school is located at the top of the island's Hill of Hope, on the site of the Byzantine-era Monastery of the Holy Trinity. The premises of the school continue to be maintained by the monastery and are used to host conferences. It is possible to visit the island where it is located via boat in approximately one hour from the shore of Istanbul. An international campaign to reopen this theological school is ongoing.

İsmet İnönü House Museum is a house museum in Istanbul, Turkey. The house is in Heybeliada, the second largest island of the Princes' Islands in Istanbul. The house, then known as Mavromatis Mansion (from the Greek family of Mavromàtis), was built in the 19th century.In 1924, it was rented by the former prime minister İsmet Pasha, during the 3rd government of Turkey, in which he left his seat to Fethi Bey. However, in 1925, he returned to his former post. Beginning by 1925, the house was used by İsmet Pasha's family as a summer residence. In 1934, İsmet Pasha who has adopted the surname "İnönü" bought the house. The household furniture was donated by Atatürk, the president. In 1937, İsmet İnönü resigned from his post, and began living mostly in Heybeliada. The next year however, he was elected as the president, and began spending the vacations in other places, so the house lost its past liveliness. When ismet İnönü lost the 1950 general elections, the house once again returned to its former liveliness.İsmet İnönü died on 25 December 1973. The family kept the house. Finally, it was decided to transform the house into a house museum, keeping the original furniture. The garden of the house is used by the Museum of the Princes' Islands.

Its name, meaning 'with a saddlebag' in Turkish, in supposed reference to the valley between two hills. The island was known as Halki, Halkitis (Greek: Χαλκίτις) and Demonesos (Δημόνησος) in antiquity, the first two toponyms deriving from the Greek word halkos (Greek: χαλκός), meaning copper.

However, as tourism steadily increased animal-rights activists became increasingly concerned about the horses' welfare and so the phaetons were withdrawn in favour of electric vehicles.The island is served by Şehir Hatları ferries from Kabataş and Eminönü on the European side of İstanbul and Kadıköy and Bostanci on the Asian side.

The Princes' Islands (Turkish: Prens Adaları; the word "princes" is plural, because the name means "Islands of the Princes", Greek: Πριγκηπονήσια, Pringiponisia), officially just Adalar (English: Islands); alternatively the Princes' Archipelago; is an archipelago off the coast of Istanbul, Turkey, in the Sea of Marmara.

Burgazada, or Burgaz Adası (Burgaz for short), is the third largest of the Princes' Islands in the Sea of Marmara, near Istanbul, Turkey. It is officially a neighbourhood in the municipality and district of Adalar, Istanbul Province, Turkey. Its population is 1,655 (2022). In the past, it was called Antigoni (Greek: Αντιγόνη) after Antigonus I Monophthalmus, the father of Demetrius I of Macedon, one of the Diadochi (Successors) of Alexander the Great, who built a fort (Greek: Pyrgos for fort/tower) here. The name Burgas is thought to be derived from Pyrgos. The island covers an area of 1.5 mi² and is dominated by a single hill, Bayraktepe (Flag Hill, 170m/558ft), also known as Hristos Tepesi (Christ Hill). In 2003, a terrible fire decimated most of its woodland. Visible just offshore is tiny uninhabited Kaşıkadası (Spoon Island). There are great views back towards the mainland from the remote Kalpazankaya ("Counterfeiter's Rock" in Turkish).Historically, the island was mainly inhabited Greeks and in the 20th century many Jews from Istanbul settled here. However, with the dwindling of Turkey's minorities, the make-up of the local population is now virtually indistinguishable from the rest of Istanbul. Şehir Hatları ferries connect the island with the mainland from terminals at Eminönü and Kabataş on the European side of Istanbul and from Kadıköy and Bostancı on the Asian side. Most of the ferries call at Burgaz after Kınalıada and before Heybeliada and Büyükada.

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.

The Prinkipo Greek Orphanage (Turkish: Prinkipo Rum Yetimhanesi, also known as Prinkipo Palace or Büyükada Greek Orphanage) is a historic 20,000-square-meter wooden building on Büyükada, one of the nine Princes' Islands off the coast of Istanbul, Turkey, in the Sea of Marmara. It is considered the largest wooden building in Europe and second largest in the world. It served as an orphanage from 1903 to 1964.
