A guided walk through Tehran’s Grand Bazaar is an immersion into the commercial and social heart of the city, a labyrinth of covered lanes stretching for kilometres. With a knowledgeable guide, visitors navigate corridors devoted to carpets, gold, spices, copperware and textiles, pausing at historic caravanserais, mosques and tea houses hidden within. Rich in history, colour and the buzz of trade, the bazaar is best understood with someone who can explain its workings, making a guided visit a fascinating introduction to old Tehran.
