Alba Iulia: A Guide to Romania's Star-Shaped Citadel

Alba Iulia is a city of layered history, often called the spiritual capital of Romania. Its crown jewel is the Alba Carolina Citadel, a star-shaped fortress built in the early 18th century that remains one of the largest and best-preserved of its kind in Europe. For travellers seeking a mix of military architecture, religious heritage and relaxed Romanian charm, Alba Iulia makes an excellent stop.

The Alba Carolina Citadel

Constructed between 1715 and 1738 under Habsburg rule, the citadel follows the defensive principles of French military engineer Vauban. Covering nearly 100 hectares, it features seven bastions and six ornate gates. Visitors can stroll along the grassy ramparts, admire the intricate stonework, and watch the changing of the guard ceremony in front of the Third Gate. The citadel is open to the public and its wide pedestrian avenues are perfect for a leisurely walk.

Historic Cathedrals

Alba Iulia is home to two significant cathedrals. The Orthodox Coronation Cathedral was built in 1921–1922 to commemorate the unification of Transylvania with Romania in 1918. It was here that King Ferdinand and Queen Marie were crowned monarchs of Greater Romania in October 1922. The church is a fine example of Neo-Byzantine architecture. Nearby, the Roman Catholic Cathedral of Saint Michael is the oldest cathedral in Transylvania, with origins dating to the 11th century and a Gothic reconstruction in the 13th century. Its austere interior and long history provide a striking contrast.

Museums and Monuments

The National Museum of the Union, housed in the 19th-century "Babylon" building inside the citadel, traces the story of Romanian unification and regional history. Outside the citadel, the Unification Monument symbolises the 1918 union. Also worth a look are the Apor Palace and the Batthyaneum Library, which holds rare manuscripts and an astronomical observatory.

Around the Citadel

Alba Iulia is a compact, walkable city with a laid-back atmosphere. The citadel's former moat has been transformed into a pleasant green space. For those wishing to extend their stay, the nearby Apuseni Mountains offer excellent hiking and opportunities to experience rural tourism.

Practical Tips

Alba Iulia is easily reached by train from Cluj-Napoca, Sibiu, or Bucharest, with multiple daily services. The city centre is best explored on foot; a full circuit of the citadel's outer walls takes under two hours. When hunger strikes, try local Transylvanian dishes such as ciorbă de burtă (tripe soup) or papanași (fried doughnuts with sour cream and jam) at one of the restaurants in the old town.
