Arg-e Bam

Arg-e Bam is one of the largest adobe structures on Earth — an abandoned, heavily fortified citadel on the edge of the Kavir Desert in Iran's Kerman Province, likely founded between the 6th and 4th centuries BCE. For centuries it served as a caravan hub on the Silk Road and at its peak housed up to 12,000 inhabitants within layered mud-brick ramparts and watchtowers. On 26 December 2003, a magnitude-6.6 earthquake devastated the site and killed roughly 26,000 people in the surrounding city, collapsing much of what had stood largely intact for millennia. In 2004 the site was added to the UNESCO World Heritage List as an emergency measure, triggering an ongoing international restoration effort. Visitors today move through a layered ruin landscape of bazaars, mosques, a governor's palace, and military quarters — the raw mud-brick fabric offering a rare, unmediated encounter with pre-Islamic and early Islamic urban life in Iran.
