Karađoz Bey Mosque was built on the foundations of the Catholic church of Saint Stephen the Protomartyr. An Arabic foundation inscription on the mosque records that it was commissioned by Mehmed Beg b. Abu al-Saʿadat’ who was a brother of a vizier in the year AH 965 (1557-58). Some scholars have claimed that the vizier was the grand vizier Rüstem Pasha, but Rüstem Pasha is recorded as having only a single brother, Sinan Pasha.
The mosque may have been designed by the imperial architect Mimar Sinan. It is in the form of a domed cube fronted by a double portico. The three domes of the inner portico are supported by four marble columns. The outer portico has a shed roof resting on small octagonal pillars. The large 10.65 metres dome of the mosque sits on an octagonal fenestrated drum which is supported by eight-pointed arches.
The mosque was severely damaged during World War II, and faced near destruction during the Bosnian War in the early 1990s. However, Karađoz Bey Mosque, like the rest of Mostar, underwent extensive repairs between 2002 and 2004. The mosque was completely renovated and reopened to the public in July 2004.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
