Traseul celor Trei Fortificații

In Alba Iulia, the Three Fortifications Trail is a themed walk that reveals, layer upon layer, the city's more than two thousand years of history. The route follows the traces of three superimposed defence systems: the Roman camp of Legion XIII Gemina, the medieval fortification and the imposing Alba Carolina bastion fortress, built in Vauban style in the early 18th century. Markers and information panels guide you past monumental gates, walls, star-shaped bastions and historic buildings, offering a living lesson in military architecture.

The Alba Carolina citadel, the largest of its kind in Romania, today hosts museums, cathedrals and a changing of the guard in period costume. It is the best way to understand the city; the trail is outdoors and accessible, while the schedule of indoor sites varies.
