Dating back to the 13th century, it contains the tombs of important Transylvanian rulers and noble families. Nearby stands the Coronation Cathedral, where King Ferdinand I and Queen Marie were crowned as monarchs of Greater Romania in 1922. Its elegant architecture and historical significance make it one of the city's most visited landmarks. Within the citadel, visitors can admire several historic structures, including the Third Gate of the Fortress, considered the most impressive entrance to Alba Carolina Citadel.
