... because of rich history
Over the course of history, beside Serbs, Belgrade was ruled by Celtic tribes, Roman Empire, Byzantine Empire, Huns, Ostrogoths, Gepids, Avars, Bulgarian Empire, Hungarian Kingdom, Ottoman Empire, Habsburg (Austrian) Monarchy, and Nazi Germany.
In the 15th and 16th century two great battles were fought for Belgrade, between the Serbs and the Hungarians on one side, and the Ottoman Turks on the other. Throughout the 18th century Belgrade was bombarded and destroyed almost simultaneously by the Austrians and the Ottoman Turks. Then in the 19th century Serbs and Ottomans battled over it. In the Great War (World War I) it was severely bombarded by the Austrians. In the World War II it was bombarded on two occasions, first by the Germans, and in the end by the Allies. Both times the city was demolished almost to the ground. In addition to all of that, Belgrade is the only European city that was bombed after the World War II (in 1999) and you can still see the remains of that in the very center of the city.
