Isfahan's tree-lined boulevards, Persian gardens and iconic Islamic buildings deliver the city's reputation as a living museum of traditional culture. Many of the top sights are in the sprawling Naqsh-e Jahan, one of the world's largest public squares. It holds the Masjed-e Shah, a mosque covered in vibrant, blue-tiled mosaics and an absolute masterpiece of Safavid-era architecture. The Kakh-e Ali Qapu is also here, a six-storey palace with plenty to explore including an elevated terrace, throne room featuring original decoration, and a top-floor music room with stucco walls. Get a sense of the glories of the former capital of Persia by slowly crossing the historic bridges of the Zayandeh River at sunset – there's a wonderful social scene along the riverbanks, especially on Fridays, when families boat, stroll and picnic in this scenic setting.
