The impressive Vauban citadel structures of the 17th – 18th century warfare era, with their characteristic star shape and diamond profile bastions, are usually associated with Western Europe defence architectural tradition perfected by the great French military engineer Sébastien Le Prestre de Vauban (1633-1707).
Less well known is the fact that remarkable Vauban type fortresses are also encountered in South East Europe, within the territory encompassed today by the state of Romania, which throughout history has been a borderland between conflicting powers that came into contact in this region.
In the 18thcentury the Ottoman Empire, the erstwhile hegemon of the Balkans came to blows with the advancing Habsburg and Russian empires in the lands between the Carpathians Mountains and the river Danube, where the principalities of Transylvania, Wallachia and Moldova, historic provinces of Romania, are located. I describe that very peculiar geopolitical situation as a triple junction point of empires. The convergence of three competing powers within those territories had a powerful influence not only on local military architecture, causing the Vauban fortress type to be widely adopted, but has also produced the odd mix of western and oriental civil architectural styles encountered in today Romania.
I will be presenting here some of the most representative such historic military architectural structures using satellite images from Google Earth, endeavouring to complement them in the foreseeable future with photographs taken in situ, as I will travel throughout Romania and visit those places. The map bellow indicates the location of the citadels mentioned in the article.
* Austrian fortresses
Austria incorporated in 1699, after the conquest of Ottoman Hungary, the autonomous Transylvanian principality and its adjacent areas (Partium, Banat). The virtually continuous warfare in this borderland with the Turks and the necessity to firmly secure the territory, determined the construction of strong Vauban fortresses to protect main towns and reinforce strategic points along the advancing front line. Thus one of the oldest and most impressive such fortresses was erected between the years 1714-38 in Alba-Iulia (Hungarian: Gyulafehérvár, German: Karlsburg) the ancient capital of the principality.
The citadel surrounds the old Roman city of Apulum, one of the oldest continuously settled places in Romania, and its grid of streets sill preserves the Roman layout. The Austrians even used blocs of stone from the old Roman defence walls.
