Old Darülfünun building (Turkish: Eski Darülfünun Binası) was a university building constructed next to Haghia Sophia in Istanbul, Ottoman Empire in the mid-19th century. It was a three-storey building in neo-Renaissance style that had a great visual impact on Istanbul's urban character. The building's designer was Swiss architect Gaspare Fossati (1809—1883), who was also responsible for extensive restoration of Hagia Sophia. After its construction as a university (Ottoman Turkish: Darülfünun) building in 1854, it was passed on to the Ministries of Finance and then on to the Ministry of Justice and Foundation. Later it was also used by the Ottoman Parliament, and finally served as Palace of Justice. It was destroyed by a fire in 1933.

Hagia Sophia (Turkish: Ayasofya; Koinē Greek: Ἁγία Σοφία, romanized: Hagía Sophía; Latin: Sancta Sophia, lit. 'Holy Wisdom'), officially known as the Hagia Sophia Grand Mosque (Turkish: Ayasofya-i Kebir Cami-i Şerifi) and formerly as the Church of Holy Wisdom (Greek: Ναός της Αγίας του Θεού Σοφίας, romanized: Naós tis Ayías tou Theoú Sofías), is a Late Antique place of worship in Istanbul, designed by the Greek geometers Isidore of Miletus and Anthemius of Tralles. Built in 537 as the patriarchal cathedral of the imperial capital of Constantinople, it was the largest Christian church of the eastern Roman Empire (the Byzantine Empire) and the Eastern Orthodox Church, except during the Latin Empire from 1204 to 1261, when it temporarily became a Roman Catholic cathedral. In 1453, after the Fall of Constantinople to the Ottoman Empire, it was converted into a mosque. In 1935, the Republic of Turkey established it as a museum. In 2020, it was reconverted into a mosque. Built by the eastern Roman emperor Justinian I as the Christian cathedral of Constantinople for the state church of the Roman Empire between 532 and 537, the church was then the world's largest interior space and among the first to employ a fully pendentive dome. It is considered the epitome of Byzantine architecture and is said to have "changed the history of architecture". The present Justinianic building was the third church of the same name to occupy the site, as the prior one had been destroyed in the Nika riots. As the episcopal see of the ecumenical patriarch of Constantinople, it remained the world's largest cathedral for nearly a thousand years, until Seville Cathedral was completed in 1520. Beginning with subsequent Byzantine architecture, Hagia Sophia became the paradigmatic Orthodox church form, and its architectural style was emulated by Ottoman mosques a thousand years later. It has been described as "holding a unique position in the Christian world" and as an architectural and cultural icon of Byzantine and Eastern Orthodox civilization.The religious and spiritual centre of the Eastern Orthodox Church for nearly one thousand years, the church was dedicated to the Holy Wisdom. It was where the excommunication of Patriarch Michael I Cerularius was officially delivered by Humbert of Silva Candida, the envoy of Pope Leo IX in 1054, an act considered the start of the East–West Schism. In 1204, it was converted during the Fourth Crusade into a Catholic cathedral under the Latin Empire, before being returned to the Eastern Orthodox Church upon the restoration of the Byzantine Empire in 1261. The doge of Venice who led the Fourth Crusade and the 1204 Sack of Constantinople, Enrico Dandolo, was buried in the church. After the Fall of Constantinople to the Ottoman Empire in 1453, it was converted to a mosque by Mehmed the Conqueror and became the principal mosque of Istanbul until the 1616 construction of the Sultan Ahmed Mosque. Upon its conversion, the bells, altar, iconostasis, ambo, and baptistery were removed, while iconography, such as the mosaic depictions of Jesus, Mary, Christian saints and angels were removed or plastered over. Islamic architectural additions included four minarets, a minbar and a mihrab. The Byzantine architecture of the Hagia Sophia served as inspiration for many other religious buildings including the Hagia Sophia in Thessaloniki, Panagia Ekatontapiliani, the Şehzade Mosque, the Süleymaniye Mosque, the Rüstem Pasha Mosque and the Kılıç Ali Pasha Complex. The patriarchate moved to the Church of the Holy Apostles, which became the city's cathedral. The complex remained a mosque until 1931, when it was closed to the public for four years. It was re-opened in 1935 as a museum under the secular Republic of Turkey, and the building was Turkey's most visited tourist attraction in 2015 and 2019. In July 2020, the Council of State annulled the 1934 decision to establish the museum, and the Hagia Sophia was reclassified as a mosque. The 1934 decree was ruled to be unlawful under both Ottoman and Turkish law as Hagia Sophia's waqf, endowed by Sultan Mehmed, had designated the site a mosque; proponents of the decision argued the Hagia Sophia was the personal property of the sultan. This redesignation drew condemnation from the Turkish opposition, UNESCO, the World Council of Churches, the International Association of Byzantine Studies, and many international leaders.

The Hodegon Monastery (also Monastery of the Panaghia Hodegetria or Monastery of the Hodegoi) in Constantinople was allegedly founded by Saint Pulcheria (399–453), a daughter of Emperor Arcadius. The monastery is considered one of the three main Marian foundations built in the city along with the Blachernai and the Chalkoprateia.The monastery was situated beyond the Chalkoprateia by the sea and served as the counterpart of the Blachernai so that these structures bracket the city of Constantinople as well as the processions such as the weekly Blachernai procession that began at the Theodosian walls and ended at Chalkoprateia. The Hodegon Monastery is believed to be named after the term hodegoi, which referred to the guides who led the blinds toward the miraculous well within the structure.Tradition states that the monastery held the Icon of the Hodegetria, believed to have been painted by Saint Luke. According to an account by Xanthopoulos, this relic was brought from Antioch. While it was at Hodegon, Ruy Gonzales de Clavijo described it sometime in 1403 to 1406 as a painting with a square panel that was covered with precious stones such as emeralds, sapphires, topaz, and pearls. When the icon was sent to Pulcheria, she took a vow of chastity. The name of the icon, Panagia Hodegetria ("She who shows the Way"), is given through the legend which tells that nearby the church of the monastery was a source where the blind and all who suffered eye disorders came to be healed, since the Holy Virgin would have appeared to two blind people and guided them here where she restored their vision. The sanctuary was rebuilt by Emperor Michael III (842–867) but today only a few ruins are visible near Gülhane Park.

The Hagia Irene today operates as a museum and concert hall.

The Augustaion (Greek: Αὐγουσταῖον) or, in Latin, Augustaeum, was an important ceremonial square in ancient and medieval Constantinople (modern Istanbul, Turkey), roughly corresponding to the modern Aya Sofya Meydanı (Turkish, "Hagia Sophia Square"). Originating as a public market, in the 6th century it was transformed into a closed courtyard surrounded by porticoes, and provided the linking space between some of the most important edifices in the Byzantine capital. The square survived until the late Byzantine period, albeit in ruins, and traces were still visible in the early 16th century.

Soğukçeşme Sokağı (literally: Street of the Cold Fountain) is a small street with historic houses in the Sultanahmet neighborhood of Istanbul, Turkey, sandwiched in-between the Hagia Sophia and Topkapı Palace. The car-free zone street is named after the fountain situated at its end towards Gülhane Park. The wooden, two or three-storey Ottoman houses consisting of four to ten rooms date to the 19th to 20th century, and have been restored with the initiative of Çelik Gülersoy in 1985-1986. Called "Ayasofya Konakları" (Hagia Sophia Mansions), nine of the houses are part of the hotel Hagia Sofia Mansions Istanbul, Curio Collection by Hilton. The houses are named after the flower shrubs next to them as "Yaseminli Ev" (Jasmine House), "Mor Salkımlı Ev" (Wisteria sinensis House), "Hanımeli Ev" (Honeysuckle House) etc. The buildings are decorated in the 19th-century style with furniture including such items as beds and consoles, silk curtains, velvet armchairs and gilded mirrors. Most notable guest of the hostel was Queen Sofía of Spain, who stayed in the spring of 2000 for four nights.The birthplace of Turkey's 6th president Fahri Korutürk (1903–1987) is also situated in this street. One of the houses hosts the library "İstanbul Kitaplığı" with over 10,000 books about Istanbul owned by the Çelik Gülersoy Foundation. On one end of the street towards Gülhane Park is a Byzantine cistern, which houses the "Sarnıç Restaurant" today.
