Situated at the junction of two international rivers, Danube and Sava, Belgrade offers great opportunities for river cruising. The Confluence itself represents one of the most attractive places in the city, just below the Belgrade Fortress, and right next to the Great War Island, an oasis of untouched nature. The river banks never sleep: on numerous floating restaurants and clubs, visitors can enjoy the view, fish specialities, and local beverages.

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.

The oldest surviving building of the Namibian capital was originally built to house the German colonial troops in the late 19th century, later going on to become a museum for Namibia's struggle for independence, as well as a historic landmark in itself. The controversial Reiterdenkmal, an alleged symbol of German dominance in the region, has been relocated from its original place opposite the Christuskirche into the yard of Alte Feste for storage. The interior space is closed for public visits as of mid-2019; a few wartime exhibits are showcased out front.
