Mosque of Ibn Tulun
Congregational mosque in Cairo, Egypt, built by Ahmad ibn Tulun, who founded the Tulunid state, in his new capital al-Qata'i. Its minaret has a spiral staircase on the outside, a form that the Discover Islamic Art database links to the Great Mosque of Samarra. A slab found in the mosque gives Ramadan 265 AH (April–May 879 CE) as the date of completion.
