Bagh-e-Ghoushkhane minaret is a historical minaret in Isfahan, Iran. This minaret dates back to the 14th century. In the olden days it was in the neighborhood of the old city gate.
Because of its proximity to the tomb of Ali-ebn-e-Sahl it is also known as Ali-ebn-e-Sahl minaret. Its newest famous name is Bagh-e-Ghoushkhane minaret, because of its proximity to the Ghoushkhane garden.
A part of its vertex and tiles have collapsed.
