Humans have inhabited the ridge over the confluence of the Sava and Danube for over two millennia. The core of today’s capital city is the Belgrade Fortress and the Kalemegdan Park. They form a unique spatial entity with clearly visible remains of the Fortress divided into Upper and Lower Town, with two distinct styles. Elements of mediaeval architecture combine with dominant baroque solutions, typical for the 18th century. The Kalemegdan Park, split in two as the Great and Little Parks, developed in the area that once was the town field. The fortress and the park together represent a cultural monument of exceptional importance, the area where various sport, cultural and arts events take place.
