The region has seen various historical and military commemorations. In Serbia, the Petrovaradin Fortress marked 334 years since its foundation in 1692. Built under Habsburg Emperor Leopold I to protect southern borders, the site is known as the ‘Gibraltar on the Danube’ due to its strategic importance during the Austro-Ottoman wars.

In Croatia, the city of Petrinja observed the 34th anniversary of the establishment of the 12th Home Guard Regiment, honoring its role in the Croatian War of Independence. Concurrently, local administration began planning a new city museum to be located at the former Hotel Banija site, intended to showcase the region's history from the Military Frontier through recent earthquake recovery.
