Osijek, Croatia

Church of the Archangel St Michael (Sv Mihaela Arkandela) in Tvrda, the old citadel in Osijek, Croatia. Osijek's Tvrda was built in the form of an enormous and elaborate star-shaped fort with eight bastions, during the early 18th century. The elegant Baroque buildings in the interior form the most extensive and best-preserved ensemble of Baroque architecture in Croatia. Osijek's Tvrda has been submitted for consideration to the UNESCO World Heritage List. © Rudolf Abraham
