The mausoleum approach crosses partly rebuilt stubs of Soltaniyeh’s citadel wall and some archaeological excavations of the Mongol-era townscape.
Some 500m southwest of the main complex, the 1330 Khanegah Dervish Monastery has restored cells around a courtyard leading to the Boq’eh Chelabi-oglu Mausoleum behind the mihrab of a shattered-sided former mosque.
From the Oljeitu Mausoleum’s upper terrace, it’s easy to spot the lonely blue-domed Mullah Hasan Kashi tomb in semi-desert, 1.5km south towards the mountain skyline. It was built by Safavid Shah Tahmasp to honour Hasan Kashi, a 14th-century mystic whose recasting of Islam’s historical sagas as Persian-language poetic epics unwittingly had a vast influence over Shia Islam’s future direction.
