He is an architect who grew up in one of the most splendid periods of the Ottoman State, and who contributed to this era with his works.
Various sources state that Sinan was the architect of around 360 structures which included 84 mosques, 51 small mosques ("mescit"), 57 schools of theology ("medrese") 7 schools for Koran reciters ("darülkurra"), 22 mausoleums ("türbe"), 17 Alm Houses ("imaret"), 3 hospitals ("darüşşifa"), 7 aquaducts and arches, 48 inns ("Caravansary"), 35 palaces and mansions, 8 vaults and 46 baths. Sinan, who held the position of chief architect of the palace, which meant being the top manager of construction works of the Ottoman Empire, for nearly 50 years, worked with a large team of assistants consisting of architects and master builders.
The development and maturing stages of Sinan can be marked with three major works. The first two of these are in İstanbul - Şehzade Mosque which he calls his apprenticeship period work, Süleymaniye Mosque which is the work of his qualification stage, and Selimiye Mosque in Edirne the product of his master stage. Şehzade Mosque is the first of the grand mosques Sinan has created. Mihriman Sultan Mosque which is also known as the Üsküdar Quay Mosque was completed in the same year and has an original design with its main dome supported by three half domes. When Sinan reached the age of 70, he had completed the Süleymaniye Mosque and the Complex. This building, situated on one of the hills of İstanbul facing the Golden horn, and built in the name of Süleyman the Magnificent, is one of the symbolic monuments of the period. The diameter of the dome which exceeds 31 meters at Selimiye Mosque which Sinan completed when he was 80, is the most significant example of the level of achievement Sinan reached in architecture. Mimar Sinan has reached his artistic summit with the design, architecture, tile decorations, land stone workmanship displayed at Selimiye.
Another area of architecture where Sinan delivered unique projects are the mausoleums. Mausoleum of Şehzade Mehmed gets attention with its exterior decorations and sliced dome. Rüstem Paşa mausoleum is a very attractive structure in classical style. The mausoleum of Süleyman the Magnificent which is one of his interesting experimentations has an octagonal body and flat dome. Selim II Mausoleum with has a square plan and is one of the best examples of Turkish mausoleum architecture. Sinan's own mausoleum which is located at the north - east part of the Süleymaniye complex on the other hand, is a very plain structure.
Sinan, in the bridges he built, has master----y combined art with functionalism. The largest of his work in this group is the nearly 635 m. long Büyükçekmece Bridge. Other significant examples are Ailivri Bridge, Lüleburgaz (Sokullu Mehmet Pasha) Bridge on Lüleburgaz River, Sinanlı Bridge over Ergene River and Drina Bridge which has became the title of the famous novel of Yugoslav author İvo Andriç.
While Sinan was maintaining and improving the water supply system of İstanbul, he has built arched aqueducts at several --------s within the city. Mağlova Arch over Alibey River, which is 257 meter long, 35 meters high and displaying two layers of arches is one of the best samples of its kind
