Arad Fortress
West Region
Arad Fortress, located on the left bank of the Mureș River in Arad, Romania, is a remarkable star-shaped fortress constructed between 1762 and 1783 during the reign of Empress Maria Theresa. Designed by General Ferdinand Philipp Harsch in the Vauban-Tenaille style, the fortress features six pointed bastions with multiple underground casemates and defensive moats that could be flooded. It was strategically placed on an island surrounded by a branch of the Mureș River, connected to the city by three bridges each protected by semicircular earthworks. Inside the fortress stands the Baroque-style main gate and buildings, including the historic Franciscan Church, which was inhabited by monks until 1861. Throughout its history, Arad Fortress served as a significant military prison, detaining important figures such as Horea, Cloșca, Crișan, and French prisoners between 1790 and 1815. During the 1848–1849 Hungarian Revolution, the fortress endured a nine-month siege and was briefly occupied by revolutionary forces before being recaptured. It later held numerous prisoners of war, including Turkish soldiers and Gavrilo Princip, the assassin of Archduke Franz Ferdinand. Today, it houses the Romanian-Hungarian Mixed Peacekeeping Battalion, reflecting its ongoing military significance.
