Caravanserais (Caravansary, Caravansérail) enabled travel by caravans when there was no modern transportation. Thus, these fantastic works of architecture were important to Iran’s lucrative and critical role in commerce between Europe and China. For us, one of the joys of traveling in Iran is visiting caravanserai – the ones that have been rebuilt to their former glory and the ones that survived centuries of inattention and are awaiting rediscovery.
