Rüstem Pasha Mosque

Opened in 2012, this museum is unique and a must-see when you are in the Beyoğlu area. It was created by Turkish Nobel laureate Orhan Pamuk alongside a novel of the same name. It tells the love story of the two main characters from the novel, and represents life in Istanbul during the late 1970s to early 1980s, as it exhibits thousands of objects from that era.

A historic house museum dedicated to the life of Adam Mickiewicz, renowned Polish poet. This is where he lived while in Turkey from September 1855 to 26 November 1855, when he died of illness.

A remarkable Bulgarian Orthodox church better known as Demir Kilise, "Iron Church", as it's a cast iron prefab. The Bulgarians split from the Greek Orthodox and established their own wooden church in 1870, which burned down. The ground was too weak for a masonry or concrete structure so they opted for cast iron. The sections were cast in Vienna, shipped here and assembled, to open in 1898. The church was renovated in 2018, but the archpatriarchate building across the street remains a gaunt shell.

The original mosque was built between 1463-1470 by the Greek architect Atik Sinan, by order of Sultan Mehmet II the Conqueror, on the site of the former Church of the Holy Apostles, which had served as Byzantine Imperial burial place for a thousand years. The grand complex with eight medreses, a library, hospital, hospice, caravanserai, market, hamam, primary school and public soup kitchen was smashed again and again by earthquakes, and the present building is from 1771 to a different design. The interior is lavish, and outside is the ornate tomb of Mehmet II and his wife Gülbahar Hatun.

Istanbul's former Asia-side railway station nowadays has no trains, but is worth a look. It was built by the Germans in 1908 in a distinctive Teutonic-castle style - to make an impact on travellers from Asia about to step into Europe, and a counterpoint to Sirkeci station (also closed) on the European side which is modelled in Oriental style. It's intended eventually to make this the terminus for the high speed rail network.

This was built in the 1430s by Grecian Jews ("Romaniotes") from the city of Ohrid, now in North Macedonia. The district of Balat was a Jewish quarter, swelled from 1492 by those expelled from Spain. The synagogue is only open for pre-arranged tours.

On top of a hill overlooking the Golden Horn, this is a magnificent mosque built by Sinan in the 1550s. It was centrepiece of a large külliye, a religious complex which included madrasas, a public kitchen and a hospital.. The small cemetery east has the mausoleums of Suleiman the Magnificent and of his wife Hurrem Sultan or Roxelana.

This is an industry museum showcasing the evolution of machines. Many transport related items including a submarine, classic cars, railway carriages, an out-of-service Bosphorus ferry and a Douglas DC-3 aircraft (possible to board) are on display, among others. Also houses a typical Istanbul streetscape with its shops and all as how it would look in the past.

An attractive stairway mixing the Neo-Baroque and early Art Nouveau styles, climbing up from Bankalar St towards the Galata Tower. It was built in the 1870s by Abraham Salomon Camondo, who belonged to a prominent Ottoman-Venetian Jewish family of financiers and philanthropists.

Built circa 1200 as the Eastern Orthodox Theotokos Kyriotissa Church, after the Ottoman conquest it was handed over to the Qalandari, a Sufi sect. In the mid-18th century it was converted to a Sunni mosque, and its mosaics were plastered over. The original appearance was restored in the 1970s.

This lavish palace with 285 rooms and 43 halls was the admin centre for the Ottoman Empire in its last 60 years. The palace government block (Selamlık) includes the Imperial Mabeyn (State Apartments) and Muayede Hall (Ceremonial Hall), while the Imperial Harem was the sultan's private quarters. Also here are the Painting Gallery, Music Museum, Clock Museum and Museum of Palace Collections. Free audio guide in several languages available by the ticket office. No photography inside, no backpacks but you can leave them in the cloakroom. Allow 3 hours to see everything.

The "Polish village" was founded in 1842 by Polish settlers in the wake of the failed uprising against Russian Imperial rule, and reinforced by more settlers after every subsequent civil upheaval until Poland's independence in 1918. Most then returned, but several stayed on, adopting Turkish citizenship but maintaining their Polish language and culture. The village has houses in traditional Polish style, a 1914 little Catholic chapel, and the Church of Matka Boska Częstochowska. It's set in woodland (a nature park) and is a popular day-trip from the city. There's four restaurants and half a dozen small hotels, plus more of each in nearby Beykoz.

This was rediscovered in 2010 when an overlying building was demolished. It was built circa 430 AD to store water brought in by Valens Aqueduct. It's smaller than the better-known Basilica Cistern, but better lit, more atmospheric and less touristy.

Situated on the gentle hill overlooking the neighbourhood of Emirgan and the Bosphorus, Emirgan Park was for long the only place in the city where Istanbulites can admire the beauty of tulips. Having lost that distinction since the first decade of the 2000s as tulips are now everywhere, this is still a beautiful park with artificial ponds, small waterfalls, and impressive views of the Bosphorus. There are also cafes with open-air sections housed in pleasant former imperial hunting manors. Squirrels are there, too, in the middle of this metropolis of more than 15 million people, though you may have to look a bit deeper (or a bit upper on the branches!) to spot them.

It was built in 2001 and is the first miniature park in Istanbul (the world's largest miniature park in respect to its model area). The park hosts icons of many cultures and civilizations. Models vary from the Hagia Sophia to Galata Tower, from Safranbolu Houses to the Sumela Monastery in Trabzon, from Qubbat As-Sakhrah to the ruins of Mount Nemrut. In addition, some works that have not survived into the present, such as the Temple of Artemis, the Halicarnassus Mausoleum and Ajyad Castle, were recreated. All former Ottoman Empire in one place.

Turkey was slow to protect its antiquities and to display them properly, but in 1867 Sultan Abdülaziz toured the museums of Paris, London and Vienna and saw what was needed. The main collection is in a grand neo-classical building of 1891, with two annexes for ancient art and Islamic art. Exhibits include Sumerian tablets, pieces of the wall of Babylon, Roman statues, and the sarcophagus of Alexander the Great, which he never lay in.

A historic 3-storey house, easily distinguishable among the modern apartment buildings thanks to its brightly coloured and gracefully decorated exterior. This is where the future founder of the Turkish Republic, Kemal Atatürk rented in 1919 while staying in Istanbul before setting sail to Samsun on the Black Sea coast to start the Turkish War of Independence. Hosts Atatürk-related paraphernalia and photos.

The Byzantines built several great palaces in Constantinople and this is the only one to survive almost intact. It's from the late 13th century, in typical alternating marble and red-brick rows, and was an imperial residence: Porphyrogenitus means "born to the purple" indicating the heir to the crown. Yet it was merely an annex or pavilion within the much greater Palace of Blachernae, of which nothing else remains. It's set within the north end of the Theodosian Walls and was much bashed during the Ottoman capture. Later it was variously a menagerie, brothel, pottery, poorhouse and bottle works, then fell derelict in the 20th century. In 2021 it re-opened as a museum.

This building dating back to 1945 houses the local radio branch of the state radio and television corporation of Turkey (TRT). Not exactly an architectural pearl (although fans of the 1940s' totalitarian architecture will likely find its stately façade interesting), but it is prominent for the part it played in the political history of Turkey: It was occupied three times by the Army, in 1960, 1971, and most recently in 1980, when the radio was decidedly the broadcast type ranging most wide and far, to announce that they had launched a coup and taken over the governance of the country.

This is a completely wooden building rising up to six storeys. It is said to be the second largest wooden construction in the world and the first in Europe. On the second highest summit of Büyükada (İsatepe, "Jesus hill", 164 m asl), it lies abandoned and dilapidated amidst the pine woods, like a picture-perfect haunted manor. It was built in the late 19th century, originally intended as a luxury hotel for the passengers of the Orient Express but never served that purpose and was put in use as an orphanage by the Greek community until it was closed down in 1964, within the context of the deteriorating Turkish-Greek relations due to the Cyprus dispute. It's dangerous, not to say forbidden, to enter the building due to the damages inflicted by decades of neglect. The title holder is the Ecumenical Patriarchate, led by Bartholomew I who wants the building restored and made a global environmental research centre (he's known as the "Green Pope" due to his efforts for environmental protection), but given the long legal disputes on titleship, not to mention the enormous funds required to bring the building to life, don't hold your breath.
