The Kalenderhane Mosque stands as a remarkable testament to Istanbul’s layered history. Originally constructed around the year 1200, it first served as the Eastern Orthodox Church of Theotokos Kyriotissa. This structure showcased the religious and architectural traditions of its time, reflecting the city’s significance in the Byzantine world.
Following the Ottoman conquest of Constantinople, the building’s role changed dramatically. It was given to the Qalandari, a Sufi sect known for its distinct spiritual practices. This transformation marked a new chapter in the building’s life, as it became a place for Sufi gatherings and devotion.
By the mid-18th century, the structure underwent another significant change when it was converted into a Sunni mosque. During this period, many of its original mosaic decorations were covered with plaster, reflecting the artistic and religious shifts of the era.
In the 1970s, efforts began to restore the mosque’s original appearance. Conservation work uncovered mosaics and architectural details that had been hidden for centuries, allowing visitors today to appreciate the blend of Byzantine and Ottoman influences at Kalenderhane Mosque.

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.
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.
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 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. You need to work around prayer times.
Tiny house museum on the life of Turkish novelist Orhan Kemal (1914–1970).
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 attractive neighbourhood was home to a large Christian and Jewish population until some decades ago and still has a number of sights like two synagogues, some churches among which the Armenian Surp Krikor Lusavoriç, dozens of wooden houses and a Jewish and Christian cemetery.
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.
Completed in 1851, this houses a mantle said to have been worn by the prophet Muhammad. The mantle is displayed during Ramadan.
The avenue has little in common with Baghdad, except it was the beginning of the Ottoman-era route to that city followed by many, including Ottoman sultan Murat IV during his march upon Persia, after which he captured Baghdad. In fact, with its sidewalk cafés and Western restaurants, Bağdat Caddesi is usually considered as one of Istanbul's most western-flavoured streets, ironically located in Asia. This street is not completely pedestrianized unlike Istiklal Street, which serves a similar function on the European Side, but its broad sidewalks with tree shade offer a pleasant walk. The restaurants and cafés on the avenue are mainly upscale, but there are also some quite affordable ones scattered around occasionally. Shopping opportunities also abound. From Kadıköy, take the Bostancı-bound dolmuşes (from just south of the ferries) or the public bus #4 (its stop is near the one for the dolmuş, but separate).
A charming domed church built in 1880 at the side of Taksim Square, now uneasily contesting with Taksim Mosque for being the main landmark of the southern edge of the square.
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.
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.
