Esfahan is Iran’s top tourist destination for good reason. Its profusion of tree-lined boulevards, Persian gardens and important Islamic buildings gives it a visual appeal unmatched by any other Iranian city, and the many artisans working here underpin its reputation as a living museum of traditional culture. Walking through the historic bazaar, over the picturesque bridges and across the Unesco-listed central square are sure to be highlights of a holiday.As the country’s third-largest city, Esfahan is home to some heavy industry, including steel factories and a much-discussed nuclear facility in the outskirts of town. Inevitably, then, traffic jams are a regular occurrence. Despite these modern realities, the inner core of the city remains a priceless gem.
