The mystic Abolhassan Ali ebn-e Sahl Azhar Esfahani lived in the era of the Al-Mu'tadid, the Abbasid caliph.
The Ali ebn-e Sahl mausoleum became a meeting place of mystics and dervishes.
The larger part of the garden is under the possession of the Welfare Organisation.
Ali ebn-e Sahl's grave is located in the middle of the cross-shaped building.
The mausoleum is open to visitors every day except Thursday afternoon.
