Isfahan, also spelt Esfahan, is one of the great cities of the world. Once the capital of Persia, it was compared to Rome and Athens by the writer Robert Byron in the classic Silk Road travelogue 'The Road to Oxiana'. Today it is in the news for having the site of Iran's nuclear research facility nearby, and causing the resulting global sanctions against the country (which are now being lifted), but is really should be known for its stunning treasures.
