Športska dvorana Zrinjevac

Športska dvorana Zrinjevac does not shout for attention.

It was built in 1973 to serve physical education classes, but a southern stand with two distinctive pillars was added later so spectators could watch. The hall was renovated in 2006, which may have shifted the seating arrangement, though the exact configuration is unclear. The capacity is variously reported as 1,160 or 1,650, and the discrepancy remains unresolved.

Local clubs use the floor for sport. RK Osijek plays handball here, and the Croatian First Handball League (1. HRL) brings matches to the city. Basketball teams KK Mursa and KK Osijek, the women’s handball side ŽRK Osijek, and gymnasts from Gimnastičko društvo "Osijek" all train within its walls. A floorball club, Hokejaški klub "Kune Osijek", is also based here.

The arena also holds concerts. Bryan Adams played an evening on November 27, 2006, that was widely reported as a major success, with the crowd reportedly spilling beyond the planned capacity. He reportedly told the audience, "You are crazy Croatians! Bravo! Thank you!" Other performers include Goran Bare & Majke in February 2025, Haris Džinović in November 2024, and Damir Urban & 4 in December 2023. The Euro Show Dance Challenge was held here in 2011.
