The Bayezid mosque in Bursa, built by architect Jakub Shah or Hayreddin Pasha in 1500-1506, at the behest of the son of Mehmet the Conqueror, Sultan Bayezid II (ruled: 1481 - 1512) – ancient, but at the same time bright and original, impressive building, which gives an idea about the architectural style of the Ottomans from the middle Ages, though not distinguished by the elegance of the Green mosque and not so lavishly decorated.

It is the oldest surviving mosque Sultan mosque in the city, erected in the transition style from renniassance to the classic, heavily influenced by the architecture of the Cathedral of Ayia Sofia. It is the one of the largest in Istanbul and has two minarets, decorated with brick patterns. It is located in the old part of town Istanbul Beyazit square (the current name of the square — Freedom Square or the Hurriyet once called). Near the gate of the mosque the Grand Bazaar Beyazit and the main gate of Istanbul University. The diameter of the dome is 17 meters. The minarets are decorated with a brick pattern.

The mosque reflects the fashion of the construction of the domed structures. Of particular interest is the front yard of a rectangular shape with arches. The entrance to the mosque is decorated with gates, feature rich and luxurious stalaktitoobraznym ornaments and inscriptions, reflecting the impact of the Seljuks in the architecture of the building. 25 domes resting on 20 antique columns, made of red porphyry and pink granite. The diameter of the dome is 17 meters.

Architectural feature of the mosque Bayezid is the combination of the original styles of the mosques of Bursa and mosques erected in postneonates period. On the Eastern and Western parts of the front of the dome are the half-dome, supported by four massive columns with stalactite finial in the form of ivory feet and 2 columns of porphyry marble. During construction of the facility is widely used columns made of marble, granite, porphyry and other construction elements borrowed from ancient (380-393 years) the Byzantine forum of Theodosius.

The first interesting feature of the mosque is that the minarets removed from each other by a distance of about one hundred meters. The second feature is that this mosque, like most of the mosques built in Renaissance period, was originally created to place the merchants, pilgrims and wandering dervishes.

Unlike mosques of the Seljuk era, the pool (or as it is called by the Turks - Adrian) placed outside the premises of the courtyard. Color harmony arcade around the courtyard and the marble coating is worthy of special attention. Two sides of the mosque built the seref (the balcony of the minaret from which the muezzin calls to prayer), which is located at a height of 87 m. the eight minarets red stripes, which give the mosque a special flavor.

It should be noted that trees from construction sites were not removed by the Turkish builders, so in the courtyard of the mosque of Bayezid at the present time there are several cypress trees, giving a very picturesque view of the whole ensemble.

The plan of this building is very interesting. The right and left of the entrance to the building of the mosque you can see the 2 wings that form a kind of porch with arcades, with sharp arches. Standing on the extreme point of one of these rabbets you can enjoy the Grand spectacle that is a long vaulted gallery in the form of a 25-year-domed portico and reminiscent of monastic refectories of the middle ages. Ottoman architects were covered dome of the mosque with lead plates, and the spire was erected a Golden Crescent. Despite the fact that the mosque is among the burial, the tomb or the tomb is located behind the mosque.

Four small domes located on each of the side aisles, which were separated by columns. Around all of the domes and semi-domes were painted ornaments, reminiscent of the patterns on the fabrics, similar to the explanation of patterns applied to tents of nomadic urokov - the ancestors of the Ottomans. The rise of Mahfil of Hunkar, destined for the ruler hunkar was executed in a very graceful manner. In the mausoleum, which represents an octagonal turbo made of rough unhewn stone, the back of the mosque, near the tomb of Sultan Bayezid, rests Selcuk Hatun. In the third tomb in 1857 buried very famous person period Tanzimat - Great Reshid Pasha.

The caravanserai and the imaret, which was considered a charitable institution in the Ottoman Empire, now owned by the city library, and in the madrasah, which is located to the West of the mosque, now houses the Museum of calligraphy. Among several mausoleums located on the South side of the mosque, is the tomb of the founder of the mosque of Sultan Bayezid II.
