History
The Palace of the Porphyrogenitus is a Byzantine imperial residence in Istanbul, Türkiye, associated with the late thirteenth-century Palaiologan period. It formed part of the Blachernae Palace complex, which served Byzantine emperors from the twelfth century onward, and is the only substantially surviving portion of that complex. The building is regarded as a relatively well-preserved example of late Byzantine architecture.
Blachernae and the Palaiologan Court
The Blachernae Palace complex was almost entirely burned and destroyed during the Latin occupation that began in 1204. After Constantinople was recovered in 1261, Emperor Michael VIII Palaiologos restored the complex and moved the imperial court there. The Palaiologan dynasty, the Byzantine imperial house that ruled from 1261 until the Ottoman conquest in 1453, shaped the period with which the surviving palace is generally associated.
The exact date of construction remains uncertain. Older building elements may have been incorporated into the structure, while differences in its masonry and the division of its spaces indicate that separate parts were built at different times. Constantine Palaiologos, the son of Michael VIII, was born there. The name “Porphyrogenitus,” meaning “born in the purple,” referred to a child born to a reigning emperor and became associated with the building because of Constantine’s birth.
The Final Byzantine Years
During the final years of the Byzantine Empire, Blachernae Palace had fallen into ruin amid dynastic struggles, and the emperors were living in the Palace of the Porphyrogenitus. Early fifteenth-century maps by Buondelmonti present it as the only imperial palace. Its position beside the outer walls made it vulnerable when the Ottomans conquered Constantinople in 1453. The palace suffered major damage, was partly demolished, and did not continue as a palace under Ottoman rule.
Its late Byzantine function as an imperial residence gave the building the Ottoman name Tekfur Sarayı. “Tekfur” derives from an Armenian word for “king” and was used for Byzantine local rulers. European usage later included the names Palace of Constantine and Palace of Porphyrogenitus. After the conquest, Jewish families from the area around Thessaloniki were settled near the palace. In the sixteenth century, the palace and an old nearby cistern housed the sultan’s menagerie. The building later served as a brothel and as a Jewish almshouse.
Ottoman Industrial Uses
In 1719, Grand Vizier Damat İbrahim Paşa ordered a tile workshop to be established in the palace courtyard. Craftsmen from İznik operated the workshop, continuing a tradition of glazed ceramic production associated especially with İznik in northwestern Anatolia. In 1721, chief architect Mehmed Ağa added workshops, a kiln, and a mill. The production continued when tile manufacture at İznik and Kütahya had nearly stopped, and the workshops remained active for about fifteen years before closing in 1735. Their tiles were used at the Fountain of Sultan Ahmed III, Kasımpaşa Mosque, and Hekimoğlu Ali Paşa Mosque.
The northern part of the palace became a glass factory during the nineteenth century. A nearby mosque endowed by Adilşah Kadın, a member of the Ottoman imperial household, in 1805 was called Şişehane Mosque, probably because of its association with the factory. The road along the eastern and southern sides of the palace also became known as Şişehane Street. A fire in nearby Jewish houses in 1864 severely damaged important parts of the building, including marble architectural elements, interior fittings, and the southeastern balcony. The glass factory was still operating in the northern courtyard, where its waste substantially raised the courtyard level.
Excavation and Restoration
By the beginning of the twentieth century, the palace was a ruin consisting of four walls. In 1955 it was placed under the administration of the Hagia Sophia Museum. The glass factory was relocated, and rubble was cleared from the courtyard so that its earlier level could be exposed. Repairs carried out between 1955 and 1970 helped keep the structure standing.
Surface investigations seeking the tile kilns began in 1993 under Filiz Yenişehirlioğlu. From 1995, collaborative excavations supervised by the Turkish Ministry of Culture and the Museum of Turkish and Islamic Arts continued until 2001. These excavations exposed additional remains and recovered tiles, glass, and pottery. Restoration between 2005 and 2014 was followed by the building’s opening as the Ottoman Tile Museum under the Istanbul Metropolitan Municipality. By 2023, the restored palace was functioning as a museum, with one tower accessible as a viewing platform. Criticism has concerned aspects of the archaeological work and the authenticity of some restored elements.
Remains
The palace stands in the Edirnekapı area of Fatih, Istanbul, at the northern end of the Theodosian Walls. These were the principal land fortifications of Constantinople, built and expanded along the city’s western side. The palace occupies the space between the inner and outer walls, beside a sharply angled wall tower and a thick rectangular tower probably built during the Middle Byzantine period, the central phase of Byzantine history from the seventh to the twelfth centuries.
Palace Building and Courtyard
Three-Storey Residence
The rectangular building is arranged around a courtyard and rises three storeys. Its walls are built of pale küfeki limestone and brick, a combination widely used in historic Istanbul architecture. Brickwork is combined with white marble and tile inlays, an ornamental treatment associated with Palaiologan architecture.
At ground level, a colonnaded arcade of four arches opens toward the courtyard. The second storey has five large windows and a long balcony on the eastern side. The upper storey may have contained a throne room extending through two storeys. Wooden floors probably separated the levels. The ground and upper floors are thought to have been used by service personnel, while the middle floor may have served as the imperial residential level when the emperor used the building.
Southern Tower and Chapel
The palace frontage and courtyard were associated with three towers. The southern tower stands at an angle to the building. A wall and arch protected the angle between them, and a doorway stood at their junction. A balcony is thought to have projected from the eastern façade overlooking the city. An Ottoman map of Constantinople by the cartographer Piri Reis depicts the palace with a double-pitched roof, a balcony on the adjoining tower, and a canopy protecting it, providing a historical representation of its appearance.
The southern wall contains the remains of a chapel. Marble architectural decoration, a marble column capital, and other marble fragments survive among the remains. The building was formerly without its interstorey floors and roof. Modern restoration used contemporary materials, and the authenticity of some reconstructed elements has been questioned.
Gates and Defensive Setting
Xylokerkos Gate
A gate at the junction of the southern tower and the palace has been identified as the Xylokerkos Gate, also called the Circus Gate or Kerkaporta. The identification and relationship between these names remain uncertain. The gate led through the palace courtyard from the city toward the outer defensive area and a bridge over the moat. It was associated with access to a wooden hippodrome or circus south of the city.
Porphyrogenitus Gate
A separate wicket gate in the western wall of the courtyard, between the second and third towers, is known as the Porphyrogenitus Gate or Regia. Built between 1143 and 1180, it connected the Blachernae district and the suburbs with the palace. After passing through the walls, it gave access to the rear of the building.
Tile Workshops and Archaeological Remains
The courtyard contains remains associated with the palace’s Ottoman tile-production phase. These include tile kilns, workshops, a furnace, and a mill. The level of the courtyard was raised by waste from the nineteenth-century glass factory before later clearance exposed the earlier surface. Excavations also recovered tiles, glass, and pottery, linking the surviving industrial remains with the building’s later uses.
The museum displays the excavated tiles, glass, and pottery, and includes a holographic animation explaining pottery production. Together with the restored palace walls, the courtyard remains preserve evidence of the site’s transformation from a late Byzantine imperial residence into an Ottoman manufacturing complex and, later, a museum.
