Stari Most in the context of "Stonemasonry"

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.

Mostar (pronounced [mǒstaːr] ) is a city and the administrative centre of Herzegovina-Neretva Canton of the Federation of Bosnia and Herzegovina, an entity of Bosnia and Herzegovina, and the historical capital of Herzegovina.

Mostar is situated on the Neretva River and is the fifth-largest city in the country. Mostar was named after the bridge keepers (mostari) who guarded the Stari Most (Old Bridge) over the Neretva during the Ottoman era. The Old Bridge, a UNESCO World Heritage Site, commissioned by Suleiman the Magnificent in the 16th century, is one of Bosnia and Herzegovina's most visited landmarks, and is considered an exemplary piece of Islamic architecture in the Balkans.

Mimar Hayruddin (Hayruddin the architect; born c. 1500) was an Ottoman chief architect (Turkish: mimar) and civil engineer under the rule of Sultan Bayezid II (reigned 1481-1512/AH 886-918) and Sultan Suleiman the Magnificent (reigned 1520-1566).

A student of the celebrated Ottoman architect Mimar Sinan, Hayruddin was responsible for the construction of the Stari Most (Mostar Bridge) in the city of Mostar in Bosnia and Herzegovina, the Bayezid II Mosque in Istanbul, the Külliye Complex of Sultan Bayezid II in Edirne, and another in the town of Amasya.
