The World's Longest Stone Bridge: UZUNKOPRU / Aerial Cinematic Footage DJI MAVIC MINI

The bridge was built between 1426 and 1443 by head architect Muslihiddin on the orders of Ottoman Sultan Murad II. The ancient stone-built bridge with 174 arches, is 1,392 m (4,567 ft) long and up to 6.80 m (22.3 ft) wide. Some of the arches are pointed and some are round. When it was first completed, the structure was the longest bridge in the Ottoman Empire and later Turkey, a title which it held for 530 years until 1973, when it was surpassed by the Bosphorus Bridge  in İstanbul. However, Uzunköprü is still the longest stone bridge in Turkey. The bridge was made to cross the Ergene River, which was a natural barrier for advances into the Balkans for the Ottoman Empire; its old name was Ergene Bridge (Ottoman Turkish: Cisr-i Ergene‎). It is so long in order to cross a low-lying marshy area. The bridge was restored in 1963. The bridge was added in 2015 to the UNESCO World Heritage Site Tentative List in the Cultural category.
