Arg-e Bam in the Iranian city of Bam, is the world’s largest adobe building, with an antiquity traced back to at least the Achaemenid Empire (550–330 BC). A World Heritage Site, it flourished from the 7th to 11th centuries AD as a producer of silk and cotton garments along the Silk Road. [1280×719]

On 26 December 2003, the citadel was almost completely destroyed by the devastating Bam earthquake (6.6 magnitude), along with much of the rest of Bam and its environs. At least 35,000 people lost their lives (injuring up to 200,000), it was the deadliest natural disaster since the 1999 Vargas tragedy.

A few days after the earthquake, the then-President of Iran announced that the citadel would be rebuilt. Since its a World Heritage Site, UNESCO intervened. Italy, Japan and France played a significant role in the restoration.
