Fortress of Arad: the star-shaped Habsburg fort on the Mureș
The Fortress of Arad (Cetatea Aradului) is a six-bastion star fortress on the left bank of the Mureș, in the Subcetate district of Arad, western Romania. Built for Maria Theresa between 1763 and 1783, it is a rare, almost intact example of Habsburg military engineering, still used by the army today.
Arad’s star-shaped fortress took twenty years to build and, according to the sources, was never besieged in its first century of life. Behind its walls, however, was held Gavrilo Princip, the man who shot Archduke Franz Ferdinand.
The history of the Fortress of Arad
After the Habsburgs freed Arad from Ottoman rule in the late 17th century and the Treaty of Karlowitz (1699) set the border along the Mureș, the city became a focal point of the Military Frontier. Prince Eugene of Savoy first thought of rebuilding the old rectangular Turkish-built fortress on the right bank of the river. After consultations with the Empress, the decision was instead to erect a new and far stronger complex on the peninsula just south of the city, on the left bank.
Construction ran from 1763 to 1783 on plans by the Austrian general and architect Ferdinand Philipp von Harsch, and cost three million florins. Thousands of prisoners did the building work. The result was a six-pointed star with six bastions and 296 gunholes, three rows of brick walls three metres thick filled with earth, casemates and underground bunkers, flooded trenches fed by the Mureș, and an outer earth glacis. The walls ran for 3,180 metres. The main gate and the buildings inside were Baroque, and the barracks normally housed 2,940 soldiers, rising to 4,030 at most.
The fortress served as part of the inner system of defence of the empire, like the fortifications of Oradea and Timișoara. The German Wikipedia notes that it lost its strategic importance after the last Ottoman war and was never put to the test by a siege. Its main use became that of a military prison. From 1794 it held 1,200 French soldiers. During the Hungarian Revolution of 1848–1849 it was besieged for nine months by the Hungarian army and briefly held by it before the Habsburg troops returned. More than 500 officers were then imprisoned here, most of them sentenced to death, and 13 generals were executed on 6 October 1849 outside the east walls. The Romanian revolutionary Eftimie Murgu was also held here.
In the First World War, thousands of Serb soldiers and civilians from Bosnia and Herzegovina were detained in an improvised camp outside the fort; 4,317 of them died of typhus and ill-treatment, and a plaque at the entrance remembers them. Gavrilo Princip, who shot Archduke Franz Ferdinand in Sarajevo in 1914, was among the prisoners. After 1918 the fortress passed to Franco-Serbian and then, in July 1919, Romanian troops; a Soviet tank unit was stationed here until 1958. Today it is the base of the Romanian 191st Infantry Battalion and has housed the mixed Romanian–Hungarian peacekeeping battalion since 1999.
