Alba Carolina is a seven-pointed star of brick spread over some 70 hectares above the town of Alba Iulia. The Habsburgs built it between 1715 and 1738, right after taking Transylvania, to the plans of the Italian architect Giovanni Morando Visconti and in the Vauban system: seven bastions with 12 m walls, ravelins and counterguards between them, dry moats and six monumental gates, three facing east and three west. Over 20,000 serfs were brought in to build it, at a cost of around a million gold florins. It is the largest fortification of its kind in the country and one of the best preserved in Europe.

Two earlier fortresses stood on the same spot: the Roman camp of the Legio XIII Gemina, the core of the town of Apulum, and the medieval bishop's citadel, demolished to make way for the Habsburg star. Romanian history has been bound to these walls more than once: here, in 1785, Horea and Cloșca, leaders of the peasant uprising, were broken on the wheel; here, on 1 December 1918, the National Assembly voted the union of Transylvania with Romania; and here, in 1922, Ferdinand and Marie were crowned king and queen of Greater Romania, in a cathedral built for the occasion.

Until the 2000s the fortress was a run-down barracks. The 2009–2013 restoration, with EU funds, cleared the moats, rebuilt the gates and bridges and turned it into an urban park that you can enter freely, at any hour.
