Long before it became a mosque, this remarkable building in Istanbul was a Roman Catholic church. The story begins in 1325, when the Dominican friars constructed a large church over the site of a much earlier chapel dedicated to Saint Paul, known in Italian as San Paolo, which had been established in 1233. The Dominican Friar Guillaume Bernard de Sévérac played a key role in this development. In 1299, he purchased a house near the chapel and started a monastery with twelve fellow friars. The need for a larger place of worship soon became apparent, leading to the construction of a new church, officially named San Domenico, on or near the original chapel site.
The fate of the church changed dramatically after the Fall of Constantinople in 1453. As part of the agreements known as the Capitulations between the Ottoman Empire and the Republic of Genoa, the church, called Mesa Domenico by the Turks, initially stayed in Genoese hands. However, between 1475 and 1478, Sultan Mehmed II ordered its conversion into a mosque. Only minor architectural changes were made, and the building became known as Galata Camii, or “Galata Mosque,” and sometimes as Cami-i Kebir, meaning “Great Mosque.”
At the end of the 15th century, Sultan Bayezid II gave the building to Muslim refugees from Spain, who had fled the Spanish Inquisition and found safety in Istanbul. This connection to the Andalusian Muslims led to its current name: Arap Camii, or “Arab Mosque.” Today, it is the largest mosque on the Galata side of the Golden Horn.
Arap Camii stands out in Istanbul’s cityscape, not only for its size but also for its unique blend of cultures and styles. The mosque’s early Italian Gothic architecture sets it apart from other Ottoman mosques, and its church belfry, converted into a minaret, remains almost unchanged. The building’s long history and distinctive design make it one of the city’s most fascinating religious landmarks.

A medieval citadel on the Bosphorus at the mouth of the Göksu creek. It was built in the late 14th century to control (polite word for "choke off") shipping along the Bosphorus, which narrows to 660 m at this point. It worked in tandem with Rumeli Citadel, built some 50 years later on the European bank. It fell into disrepair but was restored in the 1990s. You can't go in, but it's a pleasant setting; the entire village is named Anadolu Hisarı after the fort and has many traditional wooden houses (yalı). Ferries along the Bosphorus call here.
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.
The defining image of Istanbul, dominating the skyline with its great dome and six minarets. Completed in 1617 for Sultan Ahmed I, it's still a working mosque, so dress appropriately and avoid prayer times. Enter via the courtyard on the SW side. You step (shoeless) into the blue-tiled prayer hall beneath the main dome and its semi-domes. The mihrab is of finely carved marble, well-lit, and the minbar (pulpit) next to it is visible from almost all parts.
A nice, organized museum with contemporary installations. It may be seen as overpriced given its small size. It also has a simple cafe.
A neo-gothic Anglican cathedral which would not be out of place in northwestern Europe, the Crimean Memorial Church was built for the Protestant community of the city by Britain in the late 19th century. It was named in honour of the soldiers died in the Crimean War of 1856, fought against Russia by the allied Ottoman and British Empires. The congregation of the church today mostly consists of Anglican East Asians and Sri Lankans resident in Istanbul.
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.
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 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.
Completed in 1851, this houses a mantle said to have been worn by the prophet Muhammad. The mantle is displayed during Ramadan.
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.
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.
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.
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.
