Since the election of President Hassan Rouhani in 2013, Iran’s tourism industry has witnessed its biggest growth since the Islamic Revolution in 1979. The growth saw an even more significant boost following the implementation of the Joint Comprehensive Plan of Action in January 2016. Indeed, in recent years, Iran has been among the most frequently suggested travel destinations worldwide. Business Insider and Bloomberg have both named Iran to be among the "Top 50" and "Top 20" destinations to visit in 2017. Official figures show the number of foreign tourists visiting Iran in 2015 topped 5.2 million — up from nearly 3.5 million in 2012 — and the booming industry has brought the country billions of dollars in revenue and created badly needed jobs.

Reihaneh Ahsanizadeh, an English-speaking tour guide in Tehran, said there has been a surge in the number of foreign tourists during the past year. “Cities such as Tehran, Esfahan, Kashan, Yazd, Kerman and Shiraz are the top destinations for foreign visitors,” she told Al-Monitor. Of these cities, Esfahan has been one of the most consistently popular choices for both local and foreign travelers due to its rich and impressive architectural sites, ranging from royal palaces to magnificent bridges. Located in Iran’s interior, Esfahan was once one of the largest and most important cities in West and Central Asia. Its position at the crossroads of the main overland trade routes contributed to its becoming the Iranian capital during the Safavid era (1502-1736). The rule of Shah Abbas (1588-1629) was a particularly prosperous time for Esfahan, and many monuments and buildings for which the city is renowned today were constructed during this time.

Esfahan’s Jame Mosque is considered the oldest and largest of its kind in Iran and a must-see for any visitor. The origins of the mosque are said to go back to the eighth century, and although it burned down in the 11th century, it was rebuilt. Since then, the mosque has been remodeled, enhanced and expanded many times, turning it into a living museum of Islamic and Iranian architecture. The mosque is commonly considered to be the first Islamic building to adapt the four-courtyard (Iwan) layout of Sassanid palaces to Islamic religious architecture. It is also considered the prototype of later mosque designs throughout Central Asia. 

Jame Mosque is one of 21 Iranian cultural and natural sites to have been registered on UNESCO’s World Heritage List; it was inscribed as such in 2012. Historic and fascinating bazaars near the mosque's doors link it to the magnificent Naghshe Jahan Square, which became a World Heritage site in 1979. The square, which used to be a polo field, is one of the largest city squares in the world. It features a number of Islamic buildings including the Masjed-e Shah and the Sheikh Lotfollah Mosque, both of which are decorated with the famous blue-tiled mosaic designs, considered by many to be masterpieces of Safavid architecture. The square also includes the fascinating Ali Qapu Palace, a six-story building with an elevated terrace, and the beautiful gateway to the old Gheisariyeh bazaar. Martina Bisaz, a Swiss photographer who visited Iran last year, told Al-Monitor, “Esfahan was a wonderful experience with so much history. Ali Qapu Palace and Sheikh Lotfollah Mosque impressed me the most.”
