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.
