Istanbul Radio House

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".

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).

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.

Although not at the size of Hagia Sophia, this is the largest active church in Turkey. It’s directly on Istiklal St, but somewhat hidden from view by its yard portal. Catholic Masses in Italian, Turkish, and English (in different days of the week).

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.

The only active Ashkenazi Synagogue open to visits and prayers.

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.

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.

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.

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.

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 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.

Among the exhibition of this museum are five thousand pieces from the Ottoman era through WWII, with the most prominent piece possibly being the huge chain that the Byzantines stretched across the mouth of the Golden Horn to keep out the Sultan's navy in 1453 during the siege of Constantinople. In the yard of the museum, the Janissary Band (Mehter Takımı), the world’s oldest military band gives concerts of march music in traditional uniforms each afternoon, at 15:00.

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.

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.
