The Arg-e Bam (, "Bam citadel") was the largest adobe building in the world, located in Bam, a city in the Kermān Province of southeastern Iran. It is listed by UNESCO as part of the World Heritage Site "Bam and its Cultural Landscape". The origin of this enormous citadel on the Silk Road can be traced back to the Achaemenid period (6th to 4th centuries BC) and even beyond.
The entire building was a large fortress in whose heart the citadel itself was located, but because of the impressive look of the citadel, which forms the highest point, the entire fortress is named the Bam Citadel.
On December 26, 2003, the Citadel was almost completely destroyed by an earthquake, along with much of the rest of Bam and its environs. A few days after the earthquake, the Iranian President announced that the Citadel would be rebuilt.
