Alba Iulia ⭐
The largest bastion fortress in Romania and the city of the Great Union.
Alba Iulia has a star-shaped citadel. Not metaphorically — Alba Carolina is an 18th-century bastion fortification, built on the Vauban system, with seven bastions that draw a perfect star when seen from above. It's the largest of its kind in Romania and, after a massive restoration, it's fully visitable and lived in.
The Great Union was proclaimed here on December 1, 1918, in the building now called Union Hall. Across the street is the Coronation Cathedral, built specifically for the coronation of Ferdinand and Marie in 1922. A few steps away, St. Michael's Cathedral, Catholic and eight centuries old, houses the tomb of Iancu de Hunedoara.
And beyond the walls, the city sits on the ruins of Apulum, one of the largest Roman cities in Dacia. Alba Iulia is where layers of history don't hide each other — you see them all in the same two-hour walk.
