Beograd is the Capital city of Serbia . It is the biggest city and the business, cultural and administrative center of Serbia . With a Population of 1.4 million people and with a very rich History which dates from the ancient times. It is located at the confluence the Sava and Danube river where the Pannonia Plain meets the Balkans. Some 115 battles have been fought over imposing, impressive Kalemegdan, and the citadel was destroyed more than 40 times throughout the centuries. Fortifications began in Celtic times, and the Romans extended it onto the flood plains during the settlement of ‘Singidunum’, Belgrade’s Roman name. The fort’s bloody history, discernible despite today’s plethora of jolly cafes and funfairs, only makes Kalemegdan all the more fascinating. A neighbourhood dating back to the days when the Habsburg Empire ruled the city, Stari Grad is a jumble of café-lined streets peppered with neo-classical and Art Nouveau buildings. Take a wander down the pedestrianised Knez Mihailova Street – one of the city’s grandest thoroughfares. The Kalemegdan Citadel is an imposing fortress by the banks of the Danube that traces its origins to the time of the Celts. A military museum recounts the history of the Yugoslav army through the ages, with grim relics of the Balkan wars of the 1990s. Communist dictator Marshal Tito lies buried in the House of Flowers – a mausoleum where nostalgic comrades regularly pay their respects. Close to the tomb is a vast collection of relay batons handed to Tito by children across Yugoslavia. A prominent feature on the skyline, the Cathedral of Saint Sava is the largest church in the Balkans – a 20th-century structure built on the site where Turkish invaders supposedly burned the relics of Saint Sava, founder of the Serbian Orthodox church.
