Historical Peninsula

Built in 1564 by Mimar Sinan for Rüstem Pasha, Grand Vizier of Suleiman the Magnificent, this small mosque has an interior covered by beautiful Iznik pottery, then at its zenith.

Imposing mosque built 1500/05. The other parts of the religious complex have found secular use.

This museum hosts the pavement mosaics of the Great Palace of Constantinople, which stretched from the Hippodrome to the coast.

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.

Built as the Church of Saints Sergius and Bacchus around 530 AD, the same time as Hagia Sophia, but their styles differ. Transformed into a mosque in the early 1500s, it's beautifully decorated, with fine marble details, and has a pleasanter atmosphere than the larger busy mosques. The adjoining madrasa houses craft shops.

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.

Built 1748-55, this launched the style we call Ottoman Baroque, with its grand central dome and pencil-thin minarets. It was copied throughout their empire and is replicated in new mosques even today. The name means "light of the Ottomans," and the interior uses light powdery decor, bathed with much more natural light than its gloomier classical predecessors. The complex also has a madrasa and the imaret (public soup kitchen).

This is a triple structure: the church of the Monastery of Pantokrator built 1118, then a public church circa 1136 plus a chapel that served as a royal mausoleum. It became a mosque and medresse in Ottoman times, but without massive alteration so it's a prime example of middle-Byzantine architecture. It's nowadays again a mosque, photogenic by day or dusk but the area should be avoided at night.

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.

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.

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.

Completed in 1851, this houses a mantle said to have been worn by the prophet Muhammad. The mantle is displayed during Ramadan.

This is modest from the outside, as the Ottomans would not permit non-Muslim religious buildings to rival the mosques. The interior is lavish but its chief importance is as the senior Eastern Orthodox church. Their Patriarchate has been housed here since 1586 when they were ejected from Agia Sophia.

This is the red-brick castle seen south of St George. Built 1881/83, it teaches the standard Turkish curriculum plus Greek language and culture, and the tower houses an observatory. No visits.

The Church of Theotokos Pammakaristos ("All-Blessed Mother of God") was built between the 11th and 12th centuries. The parekklesion or side-chapel was added maybe 1300, with rich mosaics. The main building became a mosque in 1591, named for Sultan Murad III's conquest (fetih, hence Fethiye) of Georgia and Azerbaijan: the interior was opened up, but the chapel was undisturbed and in modern times became a museum. In 2020 the entire building was proclaimed a mosque, and every scrap of Byzantine artistry was covered up, so now there's nothing worth seeing.

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.

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.

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.

Chora means countryside, and when built as a monastery in the 4th century it stood outside the Constantine walls; a century later, it was incorporated into the Theodosian walls. It was rebuilt in the 11th century then wrecked by an earthquake, so the structure and fabulous mosaics you see now are from the 14th century. When the church was converted to a mosque in 1500 the mosaics were plastered over, and only restored in 1958 when it became a museum. In 2020 it was again proclaimed a mosque but here (unlike Fethiye Mosque) they saw the sense and tourist income of preserving the mosaics. About 15 minutes before prayer times, visitors are sent out and (if they have kept their ticket) can come back around half an hour later through the main entrance. Those who attend prayer are sent out after prayer; they cannot stay to visit and can only access the parts of the chora that lead to the prayer room.

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.

Built in the early 5th century as a monastery dedicated to Saint Andrew the Apostle, in 766 it was the burial place of Saint Andrew of Crete and was later re-dedicated to him. It was rebuilt in the late 9th century and again in the 13th, then around 1490 converted into a mosque. From the 16th century it was occupied by the Dervishes, when the legend arose that a chain hung to a cypress tree in the courtyard was a truth diviner. The chain was swung between rival witnesses and the one it hit was telling the truth. The cypress stump is still standing.

Byzantine monastery complex built in 463 AD. In the 15th century it served as İmrahor Mosque, but was wrecked by fires and earthquakes. A ruin it remains, and plans to restore it as a mosque have come to nothing. You'll probably find it locked.

The Golden Gate was the ceremonial entrance through the Theodosian city walls. After the Ottomans captured the city in 1453, Mehmed II needed a stronghold for his treasures and documents. The gate was therefore bricked up and the walls reinforced into a fortress, with valuables stored in its seven towers, hence yedi kule. In the following century the treasury moved to Topkapi Palace and the fort became a prison for high-level detainees - Osman II was strangled here in 1622. It remained in use until 1837, whereupon the Golden Gate was re-opened.

A neighborhood with colorful houses and stairs all along.

Bathhouse built in 1556 by Mimar Sinan, the chief Ottoman architect, at the request of Hürrem Sultan (Roxelana), wife of Suleiman the Magnificent. It was built over the former public baths of Zeuxippus, abandoned around 713. Restored in 2011, it's now an upmarket spa.

Built in 1584, credited to Mimar Sinan but he probably only had light-touch supervision. It was astride the city's highway from Europe and very profitable, in spite of multiple earthquakes and fires. It fell out of use late 19th century but in the 21st was revived as a tourist experience.

Built in 1741, the last major hamam opened in the Ottoman era. It has ornate architecture, great service and a stellar cast of famous visitors. Prices to match, and only tourists now use it.

Established in 1777, this is one of the cheaper options. It's marble throughout and the fittings could be original. It has a mixed main section and a separate female section for the scrubbing.

Commissioned by Süleyman the Magnificent and built by Mimar Sinan in 1550, at the east edge of Süleymaniye mosque complex. It had private cubicles for distinguished visitors such as the sultan, but was mostly a standard working-class bathhouse. It was restored in 2001 and is nowadays touristy. It's the only mixed hamam in Istanbul, but mixed sessions are only for couples and families.
