Alexander’s prison is advertised as being built as a mosque and Ziaiyeh religious school and to have no connection to Alexander.

On the other hand, some believe that this is known as Alexander’s Prison because of a reference in a Hafez poem. Other alternative is that its name comes from the claim that it was built by Alexander the Great as a prison for some Persian protesters.

The complex contains a deep, circular, brick-lined pit almost ۱۰ meters in diameter resembling an ancient dungeon found at the heart of the old. There is also a well and some nooks in the courtyard.

The dome of Alexander’s prison is made of raw clay and is decorated with plaster works and golden and azure watercolor. The noteworthy architectural features of the dome are traceable in other domes dating to the Mongolian period in Iran. Each side of the domed tower is almost ۹ meters long and it rises almost ۱۸ meters tall. There is little left of the inscriptions inside the dome but from what remains it appears to be kufic writings.
