Alba Iulia Union Hall
The room where 1,228 delegates declared the union of Transylvania with Romania on 1 December 1918 — the founding act of Greater Romania's Transylvanian chapter, commemorated annually as Great Union Day (Ziua Marii Uniri, a national holiday). The Union Hall (Sala Unirii) within the Alba Carolina fortress preserves the original furniture, documents, and the Declaration of Union. Every December 1, the city hosts a national commemoration — a state-organized ritual that overlays the Habsburg fortress with Romanian national symbolism.
