Stari Most (lit. Old Bridge) is a rebuilt 16th-century Ottoman bridge in the city of Mostar in Bosnia and Herzegovina that crosses the river Neretva and connects the two parts of the city. The Old Bridge stood for 427 years, until it was destroyed on 9 November 1993 by Croatian Defence Council during the Croat–Bosniak War. Subsequently, a project was set in motion to reconstruct it and the new bridge was completed in 2004.
The bridge is considered an exemplary piece of Balkan Islamic architecture and was commissioned by Suleiman the Magnificent in 1557. It was designed by Mimar Hayruddin, a student and apprentice of architect Mimar Sinan who built many of the Sultan's key buildings in Istanbul and around the empire.
Stari Most is part of the UNESCO World Heritage Site of Old Bridge Area of the Old City of Mostar.
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.
