Esfahan has its fair share of historical wonders (some which are UNESCO World Heritage sites), but in many ways the Abbasi has become a tourist attraction in its own right. Built around 300 years ago, under the Safavid dynasty reign of Shah Sultan Husayn, it was originally used as a pit stop for merchants traveling the ancient Silk Road. 5.2 million came in 2016 and more are expected in 2017 — its more traditional offerings still have the potential to charm.
