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.
