Osijek, located on the banks of the Drava River, is just 25km upstream from the Danube. It’s the fourth largest city in Croatia and the largest Slavonian city in Eastern Croatia. Divided into two main regions – the upper town, with its imposing city square, , and Tvrđava, the preserved fortress town to the east of the town centre along the Drava River, the city’s history dates back to 1200. During its turbulent history the Ottomans sacked it in 1526 and then the Hapsburg’s came to the rescue in 1687. Until the 18th century the city’s upper and lower towns were separate municipalities. The main attractions here are Osijek’s well-preserved Baroque ambience, open spaces and dedication to preserving regional cultural traditions. In addition to city’s the main square and fort, the promenade along the Drava and a pretty pedestrian suspension bridge toward Baranja are worth seeing. Osijek has some lovely parks and even zoological gardens, along the Drava River. Summer is filled with festivals—the most eagerly awaited is the Croatian Tambura Festival in May, which attracts tambura orchestras from all over. And Osijek’s Summer Nights Festival, June-August, gives you lots of opportunities to sample the great local cuisine, crafts and other culture.

Museum of Slavonia: Housed in two separate buildings on Trg Svetog Trojstva, this museum has an exceptionally well-curated collection of findings. The renovated city guard structure at number 2, with a lovely oak-block floor and glass dome over an arcaded patio, showcases finds from Roman stones to Celtic helmets, with explanations also in English.

Gloria Maris: Housed inside vaults of the old citadel, this museum is dedicated to seashells and marine and freshwater life. It’s the labour of love of Vladimir Filipović, who has amassed around one million shells in his 48 years of collecting, from all corners of the globe.

Watermill : Osijek's newest attraction is this replica of a watermill, a wooden construction anchored on the Drava River. This EU-backed project, part of the Miller's Route that crosses through Hungary as well, makes for a lovely pit stop on the riverfront walk.

Church of St Peter & Paul: Looming over Trg Ante Starčevića, this church's 90m-high tower is surpassed in height only by the cathedral in Zagreb. Built in the 1890s, this red-brick, neo-Gothic structure features an interior with 40 elaborate stained-glass windows in Viennese style and vividly coloured frescoes by Croatian painter Mirko Rački.

Holy Trinity Monument: This elaborate baroque pillar, erected in 1729, commemorates the victims of the 18th-century plague that swept the city.

This elegant regional capital has steadily regained its poise, boosted by the booming student numbers, new hotels and restaurants and a flow of tourists. You’ll find Osijek perfect as an intriguing, cosmopolitan and enjoyable base for day trips to Slavonia's countryside and the wonderful Kopački Rit Nature Park.

Belgrade is the capital and largest city of Serbia. It's located at the confluence of the Sava and Danube rivers, where the Pannonian Plain meets the Balkans. Its name translates to "White city". The urban area of the City of Belgrade has a population of 1.23 million, while over 1.65 million people live within its administrative limits. Its metropolitan territory is divided into 17 municipalities, each with its own local council. Belgrade is classified as a Beta- Global City.

One of the most important prehistoric cultures of Europe, the Vinča culture, evolved within the Belgrade area in the 6th millennium BC. In antiquity, Thraco-Dacians inhabited the region, and after 279 BC Celts conquered the city, naming it Singidūn.

In 1521, Belgrade was conquered by the Ottoman Empire and became the seat of the Sanjak of Smederevo. It frequently passed from Ottoman to Habsburg rule, which saw the destruction of most of the city during the Austro-Ottoman wars. Belgrade was again named the capital of Serbia in 1841. Northern Belgrade remained the southernmost Habsburg post until 1918, when the city was reunited. As a strategic location, the city was battled over in 115 wars and razed 44 times. Belgrade was the capital of Yugoslavia from its creation in 1918.

During the post-war period, Belgrade grew rapidly as the capital of the renewed Yugoslavia, developing as a major industrial center. In 1948, construction of New Belgrade started. In 1958, Belgrade's first television station began broadcasting. In 1961, the conference of Non-Aligned Countries was held in Belgrade under Tito's chairmanship. In 1962, Belgrade Nikola Tesla Airport was built.

Belgrade hosts many annual international cultural events, including the Film Festival, Theatre Festival, Summer Festival, Music Festival, Book Fair, Eurovision Song Contest 2008, and the Beer Fest. The Nobel Prize winning author Ivo Andrić wrote his most famous work, The Bridge on the Drina, in Belgrade.Other prominent Belgrade authors include Branislav Nušić, Miloš Crnjanski, Borislav Pekić, Milorad Pavić and Meša Selimović.

Most of Serbia's film industry is based in Belgrade. FEST is an annual film festival that held since 1971, and, through 2013, had been attended by four million people and had presented almost 4,000 films.

The city was one of the main centers of the Yugoslav new wave in the 1980s: VIS Idoli, Ekatarina Velika, Šarlo Akrobata and Električni Orgazam were all from Belgrade. Other notable Belgrade rock acts include Riblja Čorba, Bajaga i Instruktori and Partibrejkers.

Belgrade has a reputation for offering a vibrant nightlife; many clubs that are open until dawn can be found throughout the city. The most recognizable nightlife features of Belgrade are the barges (splav), spread along the banks of the Sava and Danube Rivers. Many weekend visitors prefer Belgrade nightlife to that of their own capitals, due to a perceived friendly atmosphere, plentiful clubs and bars, cheap drinks, the lack of language difficulties, and the lack of restrictive night life regulation.

The city is home to Serbia's two biggest and most successful football clubs, Red Star Belgrade and Partizan Belgrade. Red Star won the 1991 UEFA Champions League (European Cup). The two major stadiums in Belgrade are the Marakana (Red Star Stadium) and the Partizan Stadium. The rivalry between Red Star and Partizan is one of the fiercest in world football.
