The hook
The jewel of old Persia, built around one of the largest public squares on earth and lined with tiled blue mosques, a palace, and a bazaar, a city so beautiful that a Persian rhyme calls it "half the world."
01Why it's worth it
When the Safavid shahs made Isfahan their capital four centuries ago, they built one of the most beautiful cities ever planned, and much of it survives around the enormous Naqsh-e Jahan square. On its sides stand the Shah Mosque, its dome and portal a masterpiece of blue-and-turquoise tilework, the delicate Sheikh Lotfollah Mosque, a palace with a music room, and the entrance to the labyrinthine grand bazaar. Beyond the square, ancient arched bridges span the river, gathering places where locals sing under the arches in the evening, and old neighbourhoods hide Armenian churches and teahouses. The proverb "Isfahan is half the world" was no idle boast. Persians are famously hospitable, and travellers consistently rank Iran among the warmest countries they visit, though its politics mean checking current advice before going.
02How to experience it
Give the Naqsh-e Jahan square unhurried time by day and again in the evening when families gather, and lose yourself in the bazaar off it. Walk the old bridges at dusk to hear the singers, and seek out the Armenian quarter's church and cafés. Accept the tea and conversation that come your way; the hospitality is real.
