Semnan Bazaar is the old commercial spine of the city, smaller and calmer than the famous bazaars of Isfahan or Tabriz but still useful for understanding how the historic centre fits together. Its lanes connect everyday shops, older caravanserai spaces, and the mosque quarter.
Come for a wander rather than a shopping expedition. Local sweets, dried goods, household items, and small workshops give the bazaar its texture. It is at its best when combined with the nearby Jameh Mosque and Citadel Gate as a compact walk through old Semnan.
