Isfahan or Esfahan (Persian: اصفهان [esfæˈhɒːn] ) is a city in the Central District of Isfahan County, Isfahan province, Iran. It is the capital of the province, the county, and the district. It is located 440 kilometres (270 miles) south of Tehran. The city has a population of approximately 2,220,000, making it the third-most populous city in Iran, after Tehran and Mashhad, and the second-largest metropolitan area. Isfahan is located at the intersection of the two principal routes that traverse Iran, north–south and east–west. Isfahan flourished between the 9th and 18th centuries. Under the Safavid Empire, Isfahan became the capital of Iran, for the second time in its history, under Abbas the Great. It is known for its Persian–Muslim architecture, grand boulevards, covered bridges, palaces, tiled mosques, and minarets. Isfahan also has many historical buildings, monuments, paintings, and artifacts. The fame of Isfahan led to the Persian proverb Esfahān nesf-e-jahān ast (Isfahan is half (of) the world). Naqsh-e Jahan Square in Isfahan is one of the largest city squares in the world, and a UNESCO World Heritage Site.
