Mimar Sinan

Mimar Sinan also known as Koca Mi'mâr Sinân Âğâ, 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.
