Mangana (Constantinople)

The Column of Leo was a 5th-century AD Roman honorific column in Constantinople. Built for Leo I, Augustus of the East from 7 February 457 to 18 January 474, the column stood in the Forum of Leo, known also as the Pittakia. It was a marble column, without flutes, composed of drums with a Corinthian capital, surmounted by a statue of the emperor.The column no longer exists, but fragments belonging to it were discovered in the mid-20th century in the grounds of the Topkapı Palace, including the capital and the impost block atop it, a complete column drum and some parts of a second, and the statue's pedestal, which was originally separated from the impost by a missing plinth. The remains are visible in the second courtyard of the Topkapı complex. The column's own socle, pedestal, and base are lost. The statue too may be lost, or it may be the bronze statue now known as the Colossus of Barletta in Italy.

The Column of the Goths (Turkish: Gotlar Sütunu) is a Roman victory column dating to the third or fourth century A.D. It stands in what is now Gülhane Park, Istanbul, Turkey.

The Topkapı Palace (Turkish: Topkapı Sarayı; Ottoman Turkish: طوپقپو سرايى, romanized: Ṭopḳapu Sarāyı, lit. 'Cannon Gate Palace'), or the Seraglio, is a large museum in the east of the Fatih district of Istanbul in Turkey. In the 15th and 16th centuries it served as the main residence and administrative headquarters of the Ottoman sultans. Construction, ordered by the Sultan Mehmed the Conqueror, began in 1459, six years after the conquest of Constantinople. Topkapı was originally called the "New Palace" (Yeni Saray or Saray-ı Cedîd-i Âmire) to distinguish it from the Old Palace (Eski Saray or Sarây-ı Atîk-i Âmire) in Beyazıt Square. It was given the name Topkapı, meaning Cannon Gate, in the 19th century. The complex expanded over the centuries, with major renovations after the 1509 earthquake and the 1665 fire. The palace complex consists of four main courtyards and many smaller buildings. Female members of the Sultan's family lived in the harem, and leading state officials, including the Grand Vizier, held meetings in the Imperial Council building. After the 17th century, Topkapı gradually lost its importance. The sultans of that period preferred to spend more time in their new palaces along the Bosphorus. In 1856 Sultan Abdulmejid I decided to move the court to the newly built Dolmabahçe Palace. Topkapı retained some of its functions, including the imperial treasury, library and mint. After the end of the Ottoman Empire in 1923, a government decree dated April 3, 1924 transformed Topkapı into a museum. Turkey's Ministry of Culture and Tourism now administers the Topkapı Palace Museum. The palace complex has hundreds of rooms and chambers, but only the most important are accessible to the public as of 2020, including the Ottoman Imperial Harem and the treasury, called hazine where the Spoonmaker's Diamond and the Topkapi Dagger are on display. The museum collection also includes Ottoman clothing, weapons, armor, miniatures, religious relics, and illuminated manuscripts such as the Topkapi manuscript. Officials of the ministry as well as armed guards of the Turkish military guard the complex. The Topkapı Palace forms a part the Historic Areas of Istanbul, a group of sites in Istanbul that UNESCO recognised as a World Heritage Site in 1985.

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.

Byzantium () or Byzantion (Greek: Βυζάντιον) was an ancient Greek city in classical antiquity that became known as Constantinople in late antiquity and Istanbul today.

Byzantium was colonized by Greeks from Megara in the 7th century BC and remained primarily Greek-speaking until its conquest by the Ottoman Empire in AD 1453.
