The Palace of Amir Bashtak was built by Amir Bashtak al-Nasiri, one of al-Nasir Muhammad's close khassakiya amirs and his son-in-law, in 1334-39 on the site of the Fatimid Eastern Palace (al-Qasr al-Sharqi).
It remains nearly complete in its original form, with two stories, qa'a, a small courtyard, and integrated stables which have a special gate opening onto a side street. The long facade was endowed with many windows opening onto the busiest street in medieval Cairo.
