The Emperor's Mosque is an important landmark in Sarajevo, being the first mosque to be built (1457) after the Ottoman conquest of Bosnia. It is the largest single-subdome mosque in Bosnia and Herzegovina, built in the classical Ottoman style of the era.
It was built by one Isaković-Hranušić who dedicated it to the Sultan, Mehmed the Conqueror, the conqueror of Constantinople. Considered one of the most beautiful mosques of the Ottoman period in the Balkans, the mosque features a roomy interior and high quality decorative details, such as the mihrab.
Damaged and totally destroyed at the end of that century, it was rebuilt in 1565 and dedicated this time to Suleyman the Magnificent. Side rooms were added in 1800 and connected to the central prayer area in 1848. Between 1980 and 1983 the painted decorations in the interior of the mosque were conserved and restored. The burial ground (graveyard) beside the Emperor's Mosque contains the graves of viziers, mullahs, muftis, sheikhs, the employees in the Emperor's Mosque, along with other prominent figures living in Sarajevo.
The mosque was damaged during World War II but mostly in the wars during the 1990s, and renovation work is pending.
The first settlements in Sarajevo were built around the mosque with the residence of the Sultan's representatives then being built next to the mosque. Isa-bey also built a hammam (public bath) and a bridge that led directly to the mosque. This bridge was disassembled during the Austro-Hungarian government and rebuilt just a few meters upstream where it still exists today.
On the other side of the river, he built a caravanserai. For the financing of these facilities, Isa-bey left a heritage of many shops, land and properties.
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.
