Eyüp Sultan Mosque

A neighbourhood east of Şişli known for its Art Nouveau apartment buildings, the ground floors of many of which are upmarket restaurants, cafes, pubs, and garment stores lining the sidewalks. Nobel laureate Orhan Pamuk, well-known Turkish novelist, is a lifelong resident of the neighbourhood which formed the background of several of his novels.

Built in first half of the 15th century, this is the large medieval castle under the Second Bosphorus Bridge. Its former name Boğazkesen (Turkish)/Laimokopia (Greek) means both "strait-blocker" and "throat-cutter" in both languages and denotes the reason of its building—to shut the supply routes from the Black Sea in the north into the slowly falling apart Byzantine Empire through the Bosphorus. Rumeli, literally "the Roman land", was the name of the European half of the Ottoman Empire, and as is usual with some other structures and villages along the Bosphorus, used as a prefix to differentiate Rumeli Hisarı from its counterpart in the Asian Side, the much smaller Anadolu Hisarı just across the Bosphorus.

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.

Tiny house museum on the life of Turkish novelist Orhan Kemal (1914–1970).

Feshane began as a factory producing fezzes (fes), the red hats made of felt adopted by the Ottomans in the early 19th century as a part of westernizing efforts in lieu of much more traditional turbans. However, the fez was scrapped in favour of western garments during Atatürk's reforms of the 1920s and 30s as it was thought to symbolize the old, decidedly oriental regime. A restoration in 1998 made it a cultural and exhibition center, and after another in 2023, it was reopened as a culture and art center under the name Artistanbul Feshane.

The building was erected as a Roman Catholic church in 1325 by the friars of the Dominican Order, near or above an earlier chapel dedicated to Saint Paul (Italian: San Paolo) in 1233. In 1299, the Dominican Friar Guillaume Bernard de Sévérac bought a house near the church, where he established a monastery with 12 friars. A new, much larger church was built near or above the chapel of San Paolo in 1325. Thereafter the church was officially dedicated to San Domenico. After the Fall of Constantinople, according to the Capitulations of the Ottoman Empire with the Republic of Genoa, the church, which by that time was known by the Turks under the name of Mesa Domenico, remained in Genoese hands, but between 1475 and 1478 it was transformed, with minor modifications, into a mosque by the Ottoman Sultan Mehmed II and became known as Galata Camii ("Galata Mosque") or Cami-i Kebir ("Great Mosque"). Towards the end of the century Sultan Bayezid II assigned the building to those Muslims of Spain (Andalusia) who had fled the Spanish Inquisition and migrated to Istanbul; hence the present name Arap Camii (Arab Mosque). Today, Arap Camii is the largest mosque on the Galata side of the Golden Horn. It is one of the most interesting mosques in the city due to its early Italian Gothic architectural style and church belfry, which has practically remained unaltered even after being converted into a minaret.

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 only active Ashkenazi Synagogue open to visits and prayers.

If you are already in the area, it's worth considering to visit this waterside neo-Baroque manor, built in the 19th century for the countryside and hunting excursions of the Ottoman dynasty. The area, where the Göksu River flows into the Bosphorus, was known as "the Sweet Waters of Asia" by the pioneer European travellers of the epoch (as opposed to "the Sweet Waters of Europe", another contemporary elite recreational area on the other side of the city, where the Kağıthane and Alibeyköy Rivers empty into the Golden Horn).

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.

A contemporary art museum in a building converted from an old power plant: 1914-built and coal-fired, this was the oldest in Istanbul and the Ottoman Empire. Part of the plant was kept in almost exact original condition and now serves as the "Energy Museum".

Museum in a restored building that was the stables for Topkapı Palace. It exhibits various instruments for astronomy, clocks, pumps, weaponry and so on developed in Islamic realms down the centuries, but these are modern repro, and explanations of their context are skimpy. Islamic science and technology preceded that of Europe, as they insist, but they get the tone wrong, as if that was the triumphal culmination rather than the springboard for further advance.

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.

Sokollu Mehmet Pasha was the grand vizier and de facto ruler of the Ottoman Empire during its 16th century golden age. He commissioned this mosque, one of three in the city to bear his name, but the sloping site was a challenge. He hired the best, Mimar Sinan, who completed it in 979 AH / 1571 AD, with the slope resolved by a fronting courtyard above shops and a medrese. The interior has outstanding İznik blue tiles, and three fragments of the Black Stone (Hajar al-Aswad) of the Kaaba: above the main entrance, minbar and mihrab.

The imperial enclave of the Ottoman emperors for four centuries. Lavishly decorated, with exhibitions of fine craftmanship and four courts of increasing grandeur. The second court has the Harem and the State Treasury, housing a weaponry display. The third court has the Imperial Treasury, with Islamic and Christian relics. The views from the Fourth Court over the Bosphorus are spectacular. Reckon on spending several hours here and bring water as the museum kiosk is overpriced.

It was built by the Genoese in the 14th century on the city walls of Galata, marking the highest point of their territory. Ride an elevator and take two flights of stairs to the top, then walk the parapet for a 360°-view of Istanbul, including the entire Sultanahmet peninsula: crowned by Topkapı Palace, the Blue Mosque and Hagia Sophia. A beautiful spot worthy of a lot of pictures.

This is a circular indoor space enclosed by a 3D depiction of the Ottomans breaching the Walls of Constantinople on 29 May 1453, with sound effects. It's over-priced, unhistorical and tourist-trappy.
