Bursa City Museum

The Siege of Bursa took place from 1317 until the capture of Bursa on 6 April 1326, when the Ottoman Turks deployed a bold plan to seize the city, which was back then known as Prusa. The Ottomans had not captured a city before; the lack of expertise and adequate siege equipment at this stage of the war meant that the city fell only after six or nine years.
