The Arg-e Bam, in Kerman Province in southeastern Iran, is the largest adobe building in the world and a UNESCO World Heritage Site. The ancient citadel has a history dating back around two thousand years, to the Parthian Empire (248 BC – 224 AD), but most of its buildings were constructed during the Safavid dynasty. A strong earthquake on 26 December 2003 largely devastated the fortress and the nearby modern city of Bam. The Arg-e Bam, including the governor's residence, the main tower, the Four Seasons Palace and the hammam, were nearly totally destroyed; this photograph from 2016 shows the citadel partially reconstructed.Photograph credit: Diego Delso
