Mimar Sinan (Ottoman Turkish: معمار سينان, romanized: Mi'mâr Sinân; Turkish: Mimar Sinan, pronounced [miːˈmaːɾ siˈnan]; c. 1488/1490 – 17 July 1588) also known as Koca Mi'mâr Sinân Âğâ, ("Sinan Agha the Grand Architect" or "Grand Sinan") was the chief Ottoman architect, engineer and mathematician for sultans Suleiman the Magnificent, Selim II and Murad III. He was responsible for the construction of more than 300 major structures, including the Selimiye Mosque in Edirne, the Kanuni Sultan Suleiman Bridge in Büyükçekmece, and the Mehmed Paša Sokolović Bridge in Višegrad, as well as other more modest projects such as madrasa's, külliyes, and bridges. His apprentices would later design the Sultan Ahmed Mosque in Istanbul and the Stari Most bridge in Mostar.
The son of a stonemason, he received a technical education and became a military engineer. He rose rapidly through the ranks to become first an officer and finally a Janissary commander, with the honorific title of Sinan. He refined his architectural and engineering skills while on campaign with the Janissaries, becoming expert at constructing fortifications of all kinds, as well as military infrastructure projects, such as roads, bridges and aqueducts. At about the age of fifty, he was appointed as chief royal architect, applying the technical skills he had acquired in the army to the "creation of fine religious buildings" and civic structures of all kinds. He remained in this post for almost fifty years.
