More appealing than Imamzadeh-ye Abdollah is the 1883 Imamzadeh-ye Hossein, tucked behind Hotel Yass in a little courtyard with an ancient mulberry tree. The XIII century Borj-e Qorban is a classic 12-sided, pointy-roofed tower tomb, but it looks sadly out of place in its dowdy housing-estate setting.
A vaulted passage of the bazaar leads into the courtyard of the large Qajar-era Masjed-e Jameh (Jameh Mosque; admission free). The off-line south iwan leads into a hall (currently under restoration) over which there is an impressively large brick dome. The north iwan is lavished with patterned blue tilework that continues on four of the mosque's six minarets. Some areas are restricted to men only.
Sang-e Shir, or Stone Lion, is a walrus-sized lump of rock eroded beyond recognition by the rubbing of hands over 2300 years, tentatively dated to the Parthian dynasty. Supposedly once a lion, you had never look twice at were it not the only surviving 'monument' from the ancient city of Ecbatana whose gates it once guarded. Local legend attaches all manner of significance to this strangely unmoving lump; supposedly put up by Alexander the Great to commemorate the death of his lover Hephaistion, bizarrely it now has supposed magic powers to make women pregnant!
