Sanki Yedim Mosque

Şeyh Süleyman Mosque (full name in Turkish: Şeyh Süleyman Mescidi, where mescit is the Turkish word for a small mosque) is a mosque in Istanbul converted from a former Byzantine building which was part of the Eastern Orthodox Pantokrator Monastery. Its usage during the Byzantine era is unclear. The small building is a minor example of architecture of the Byzantine middle period in Constantinople.

Kepos was a town of ancient Thrace, inhabited during Roman times.Its site is located above Melias Sinus in European Turkey.

The Aviation Martyrs' Monument (Turkish: Hava Şehitleri Anıtı or formerly Tayyare Şehitleri Abidesi), located in Fatih district of Istanbul, Turkey, is a memorial dedicated to the first soldiers of the Ottoman Airforce to be killed in flight accidents. In Turkey, one use of the term "martyr" is as an honorific for people killed in action during war. The monument was commissioned right after the consecutive crash of two monoplanes in Palestine, killing three of the four military aviators who were on an expedition flight from Istanbul to Alexandria in early 1914. The monument, in form of a column, was inaugurated in 1916. A military memorial ceremony is held in front of the monument every year on Martyrs' Day.

Eski Imaret Mosque (Turkish: Eski Imaret Camii) is a former Eastern Orthodox church converted into a mosque by the Ottomans. The church has traditionally been identified with that belonging to the Monastery of Christ Pantepoptes (Greek: Μονή του Χριστού Παντεπόπτη), meaning "Christ the all-seeing". It is the only documented 11th-century church in Istanbul which survives intact, and represents a key monument of middle Byzantine architecture. Despite that, the building remains one among the least studied of the city.

The Aqueduct of Valens (Turkish: Valens Su Kemeri, Ancient Greek: Ἀγωγὸς τοῦ ὕδατος, romanized: Agōgós tou hýdatos, lit. 'aqueduct') was a Roman aqueduct system built in the late 4th century AD, to supply Constantinople – the capital of the eastern Roman empire. Construction of the aqueduct began during the reign of the Roman emperor Constantius II (r. 337–361) and was completed in 373 by the emperor Valens (r. 364–378). The aqueduct remained in use for many centuries. It was extended and maintained by the Byzantines and the Ottomans. Initially, the Aqueduct of Valens carried water from springs at Danımandere and Pınarca; the channels from each spring met at Dağyenice. This 4th-century first phase of the system was 268 kilometres (167 miles) long. A second, 5th-century phase added a further 451 kilometres (280 miles) of conduits that took water from Vize, 120 kilometres (75 miles) away from Constantinople.: 13 The final and most visible aqueduct bridge in the system survives in the Fatih district of Istanbul, Turkey. Named in Turkish: Bozdoğan Kemeri, lit. 'Aqueduct of the Grey Falcon', it is an important landmark in the city, with its arches passing over Atatürk Boulevard (Atatürk Bulvarı). The Bozdoğan Kemeri spans the valley between the hills that are today occupied by the Istanbul University and the Fatih Mosque, formerly the site of the Church of the Holy Apostles. The surviving section is 921 metres long, about 50 metres less than the original length.

The Church of the Holy Apostles (Greek: Ἅγιοι Ἀπόστολοι, Agioi Apostoloi; Turkish: Havariyyun Kilisesi), also known as the Imperial Polyándreion (imperial cemetery), was a Greek Eastern Orthodox church in Constantinople, capital of the Eastern Roman Empire. The first structure dates to the 4th century, though future emperors would add to and improve upon it. It was second in size and importance only to the Hagia Sophia among the great churches of the capital. When Constantinople fell to the Ottomans in 1453, the Holy Apostles briefly became the seat of the Ecumenical Patriarch of the Greek Orthodox Church. Three years later the dilapidated edifice was abandoned, and the patriarchate was moved to the Theotokos Pammakaristos Church. In 1461, the church of the Holy Apostles was demolished by the Ottomans to make way for the Fatih Mosque.

The large Fatih Mosque (Turkish: Fatih Camii, "Conqueror's Mosque" in English) is an Ottoman mosque off Fevzi Paşa Caddesi in the Fatih district of Istanbul, Turkey. The original mosque was constructed between 1463 and 1470 on the site of the Church of the Holy Apostles. Seriously damaged in the 1766 earthquake, it was rebuilt in 1771 to a different design. It is named after the Ottoman sultan Mehmed the Conqueror, known in Turkish as Fatih Sultan Mehmed, who conquered Constantinople in 1453. The Sahn-ı Seman Medrese, once an important center for the study of theology, law, medicine, astronomy, physics and mathematics, formed part of the Fatih Mosque. It was founded by the Turkic astronomer Ali Qushji who had been invited by Mehmed to his court in Istanbul. The mosque complex was completely restored in 2009 and again ten years later. It reopened to worshippers in 2021.

Zeyrek is a neighborhood of Fatih district in Istanbul, Turkey. It overlooks the Golden Horn, and got its name from the Mosque of Zeyrek. It hosts also several Byzantine cisterns and the little Şeyh Süleyman Mosque, also of Byzantine origin. It is a picturesque but poor neighborhood. The center of Zeyrek is on the World Heritage List as part of the Historic Areas of Istanbul, the World Heritage Site.

Zeyrek Mosque (in Turkish: Zeyrek Camii) or Monastery of the Pantocrator (in Turkish: Pantokrator Manastırı), is a significant mosque in Istanbul, made of two former Eastern Orthodox churches and a chapel. It represents the most typical example of architecture of the Byzantine middle period in Constantinople and is, after Hagia Sophia, the second largest religious edifice built by the Byzantines still standing in Istanbul.

The Column of Marcian (Turkish: Kıztaşı) is a Roman honorific column erected in Constantinople by the praefectus urbi Tatianus (450-c.452) and dedicated to the Emperor Marcian (450-57). It is located in the present-day Fatih district of Istanbul. The column is not documented in any late Roman or Byzantine source and its history has to be inferred from its location, style and dedicatory inscription. The column is carved from red-grey Egyptian granite, in two sections. The quadrilateral basis is encased by four slabs of white marble. Three faces are decorated with IX monograms within medallions, and the fourth with two genii supporting a globe. The column is topped by a Corinthian capital, decorated with aquilae. The inscription confirms that the capital was originally surmounted by a statue of Marcian, in continuation of an imperial architectural tradition initiated by the Column of Trajan and the Column of Marcus Aurelius in Rome. The basis of the column is orientated northwest/southeast, while its capital is aligned north/south, possibly so that the statue could look towards the nearby Church of the Holy Apostles. A Latin dedicatory inscription is engraved on the northern side of the basis. Its lettering was originally filled with bronze, which has since been removed. The inscription reads: [PR]INCIPIS HANC STATUAM MARCIANI | CERNE TORUMQUE | [PRAE]FECTUS VOVIT QUOD TATIANUS | OPUS (Behold this statue of the princeps Marcian and its base,a work dedicated by the prefect Tatianus.) The Turkish name Kıztaşı, "the column of the girl" (kız: "girl" + taş: "stone"), apparently derives from the genii on the basis, which during the Ottoman period were the column's most distinguishing features (after the loss of Marcian's statue).

The Church of St. Polyeuctus (Greek: Ἅγιος Πολύευκτος, translit. Hagios Polyeuktos; Turkish: Ayios Polieuktos Kilisesi) was an ancient Byzantine church in Constantinople (now Istanbul, Turkey) built by the noblewoman Anicia Juliana and dedicated to Saint Polyeuctus. Intended as an assertion of Juliana's own imperial lineage, it was a lavishly decorated building, and the largest church of the city before the construction of the Hagia Sophia. It introduced the large-scale use of Sassanid Persian decorative elements, and may have inaugurated the new architectural type of domed basilica, perfected in the later Hagia Sophia. Little is known of the church's history after its construction. The building survived until the 11th century, after which it fell into decay, while several architectural elements were removed and reused in Constantinople and other cities. After being built over in the Ottoman period, the site of the church was rediscovered during excavations in the 1960s. The area, directly opposite the Istanbul Metropolitan Municipality City Hall, is now a preserved archaeological site open to visitors, although the sculptures have been removed to the Istanbul Archaeological Museum.

The Mosque with the Spiral Minaret (Turkish: Burmalı Mescit Camii or Burmalı Minare Camii) is a 16th-century Ottoman mosque in Şarachane park, Fatih district, Istanbul, Turkey. Built in 1550 on behalf of Emin Nuretti Efendi, qadi 'asker of Egypt, it is named for its spiraling (burmalı) brick minaret, a copy of a Seljuq design that is unique in Istanbul. The mosque is not domed, but has a pitched porch, which rests on four reused Byzantine Corinthian stone columns. Unusually, the entrance is off-center behind a column. The mosque's interior is undistinguished.
