Ali Pasha Mosque was constructed in Sarajevo, Bosnia and Herzegovina during 1560–61 for Sofu Hadım Ali Pasha, an Ottoman statesman who served as the governor of the Bosnia Eyalet of the Ottoman Empire amongst other roles, after his death in September 1560.
The mosque was built according to the classical Ottoman architectural style. A dome covers the prayer area and three smaller domes cover the cloister. Its proportions make it the largest sub-dome mosque in Bosnia and Herzegovina. The grounds of the complex contain a mausoleum (türbe) with two sarcophagi—those of Avdo Sumbul and Behdžet Mutevelić, Gajret activists who died in the dungeons of Arad. The Ali Pasha Mosque was heavily damaged by Serbian forces during the Bosnian War of the early 1990s, especially the dome. The most recent renovation of the mosque occurred in 2004 and in January 2005, the Commission to Preserve National Monuments issued a decision to add the Ali Pasha Mosque to the list of National Monuments of Bosnia and Herzegovina.
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.
