The buildings aren’t the only old things to be found in the Tvrđa. On the first Saturday of each month, antique dealers from Croatia and surrounding countries descend on Trg Svetog Trojstva to peddle their treasures. The Osijek Antiques Market, organized by the City of Osijek, Glas Slavonije and the Osijek Tourist Board, opened in 2005 in front of the Bastion and then moved to the Tvrđa’s main square. It attracts sellers from Hungary, Serbia, Bosnia and Herzegovina as well as Croatia who offer antique furniture, porcelain, paintings, clocks, coins, and antique weapons and other collectibles.
