Once a separate city, Zemun is now a renowned part of Belgrade, famous for its river taverns, unique atmosphere, and small restaurants specialising in fresh fish from the Danube. The main street of Zemun is home to the Homeland Museum and the Madlenianum Opera and Theatre. Along the Danube, Zemunski kej is a kilometre-long promenade featuring barge-cafés, an amusement park. The former largest hotel in Belgrade, Hotel Jugoslavija, now hosts the Grand Casino. At night, the barge-cafés become the epicentre of nightlife, staying open until dawn. Gardoš Tower, also known as Millennium Tower, stands as Zemun's most iconic symbol, offering panoramic views of Belgrade and a tranquil escape from urban noise. The neighbourhood has retained its authentic charm, with narrow, mostly cobbled streets and individual residential houses.

Ada Ciganlija, Belgrade's most renowned summer resort, has transformed from an island to a peninsula, becoming the city's largest and most picturesque recreational spot. The Savsko lake is encircled by over 7 km of Blue Flag-awarded beaches, offering myriad ways to enjoy hot summer days. In summer, Ada Ciganlija turns into a bustling hub, attracting over 100,000 visitors daily (up to 300,000 on weekends) for swimming, sports, or leisurely afternoons in beachside cafés. In contrast, autumn and winter bring a quieter atmosphere, with a scenic promenade lined by cafés and nightclubs, although the lake's ice is too thin for skating. With more than 50 open-air sports facilities, including a golf course and cable-ski circuit, as well as courts and pitches for various sports and extreme activities like bungee-jumping and paintball, there's no shortage of action. The area's restaurants offer traditional city fare, particularly fish specialities, while bars and floating river clubs provide vibrant nightlife.

In 1928, the famous artist Ivan Meštrović designed a sculpture for the drinking fountain on Terazije. The public was against having a nude male figure set up in the city centre, however. After World War I, the project was cancelled and thus the Victor was set up on Kalemegdan instead. The plato next to the monument is among the most crowded places in the city, where visitors love to take photos and enjoy the view over New Belgrade and Zemun.

Saarbrücken's history museum, neighbouring on the Saarbrücken Castle, presents the turbulent history of the French-German border area with special emphasis on the era following the Franco-Prussian war of 1870–71, through various permanent and temporary exhibitions.
