TheBayezid II Mosque (Turkish:Beyazıt Camii, Bayezid Camii) is an early 16th-centuryOttoman imperial mosque located inBeyazıt Square inIstanbul,Turkey, near the ruins of theForum of Theodosius of ancientConstantinople.
The Beyazid Mosque was commissioned bythe OttomanSultanBayezid II, and was the second large imperial mosque complex (orselatin mosque) to be erected in Istanbul after theconquest in 1453. The earlier imperial complex, theFatih Mosque, was later destroyed byearthquakes and completely rebuilt in a different style. As a result, the Beyazid complex is the oldest imperial complex in Istanbul that is preserved in more or less its original form, making it of considerable historical and architectural significance.[1][2]
The mosque was constructed between 1500 and 1505, with akülliye (religious and charitable complex) added immediately afterwards.[3] This included amedrese (theological college), completed in 1507; a largehamam (bathhouse), completed some time before 1507; animaret (soup kitchen); acaravanserai; and severalmausolea including thetürbe of Bayezid II himself.[3][4]
The chief architect of the mosque is not directly known. Based on Ottoman documents that mention architects during Bayezit II's reign, 20th-century scholar Rıfkı Melül Meriç identified Yakubşah ibn Islamşah as the most likely architect.[a] One of Yakubşah's assistants, Yusuf ibn Papas, finished off the work on themedrese.[3] That the architect was a nephew of theGreek architect of theFatih Mosque (Atik Sinan or Christodoulos), is known from a grant of Bayezid II.[6][verification needed] This grant confirms the endowment byMehmed II of the Greek OrthodoxChurch of Saint Mary of the Mongols, the only church in Istanbul that was never converted into a mosque, to the mother of Christodoulos (the Bayezid II Mosque's architect's grandmother) in acknowledgment of the two architects' work.[6] Little else is known about Yakubşah ibn Islamşah other than that he also built a caravansarai inBursa. However, the polished style of the mosque suggests experience with earlier Ottoman and western architectural techniques.[7]
In 19th-century and early 20th-century accounts of the city it is often referred to as "the Pigeon Mosque" because of the large number of birds that congregated nearby to be fed by worshippers.[8][9]
The dome was partially rebuilt after anearthquake in 1509,[3] andMimar Sinan conducted further repairs in 1573–74.
Theminarets were burned separately by fires in 1683 and 1754. They were also damaged by a lightning strike in 1743. A document dated October 1754 states that a special type of stone was brought fromKaramürsel to repair the mosque.[10] An inscription above the courtyard entrance suggests that repairs were also carried out in 1767 as a result ofthe earthquake which struck Istanbul in 1766.[3]
Extensive new restoration work was started in August 2012 and took eight years to complete. During the process inappropriate materials used during previous repairs were removed, and damaged materials were either cleaned or replaced. The restoration involved a team of approximately 150 people and cost 49 millionTurkish liras (approximately US $7.2 million). The mosque was reopened for worship in 2020.[11]
The mosque is oriented along the northwest-southeast axis with a courtyard to the northwest with an area almost equal to that of the mosque itself. The courtyard has monumental entrance portals on three sides and is surrounded by a colonnadedperistyle supported by twenty columns. Two of the columns are made ofporphyry, ten are ofverd antique, and six are of pinkgranite.[12] It is roofed with 24 small domes and has a pavement of polychromemarble.
The mosque itself is square measuring approximately 40 metres (130 feet) per side and its dome is approximately 17 metres (56 feet) in diameter.[12][13] The central dome is supported by twosemi-domes along the main axis and two arches running along the secondary axis. The mosque is constructed entirely of cut stone using coloured stones and marbles.
The mosque interior resembles a smaller scale version of theHagia Sophia.[1] In addition to the central dome, the semi-domes to the east and west form a nave. To the north and south there are side aisles, each with four small domes, which extend the width of the mosque, but which are not divided into galleries. The dome is supported by huge rectangular piers, with smoothpendentives andstalactite decorations. The space is lit with twenty windows at the base of the dome and seven windows on each semi-dome, in addition to two tiers of windows on the walls. An elevated sultan's loge (hünkâr mahfili), located to the right of themihrab, is supported by ten small marble columns which were reused from earlierByzantine churches.[3]
On the west side, a broad extended corridor extends considerably beyond the main structure of the building. Originally designed as four domed cells to serve as ahospice for wanderingdervishes, the wings were integrated into the prayer hall in the sixteenth century and now consist of three consecutive rooms separated by archways.[14] At the ends of these wings are the twominarets.
Behind the mosque is a small garden, containing thetürbe (tombs) of SultanBayezid II, his daughter Selçuk Hatun, andGrand VizierKoca Mustafa Reşid Pasha.[1] Below the garden is an arcade of shops (arasta), designed byMimar Sinan in 1580, whose rents were originally intended to support the mosque. It was extensively restored in the 1960s.
In 1882 the former soup kitchen was converted into the State Library of Istanbul by SultanAbdulhamid II; it now houses over 120,000 books and 7000 manuscripts.[citation needed]
The formermedrese now houses a smallMuseum of Turkish Calligraphy Art that has been closed to the public for more than a decade. In 2022 this was undergoing restoration.
The monumentalBayezid II Hamam was restored in the 2000s and early 2010s before being reopened as the Museum of Turkish Hamam Culture in 2015.[15] Embedded in the lowest part of the walls are fragments of sculpture from the lost triumphal arch from theForum of Theodosius, more remains of which are scattered on the ground across the road from the mosque. During restoration of the hamam traces of an old Byzantine church beneath the hamam were uncovered.[citation needed]
