Al-Muizz li-Din Allah al-Fatimi Street, commonly known as al-Muizz Street, is a major historic street in Cairo, Egypt. Dating back to the 10th century, it was established by the Fatimid dynasty and named after their fourth caliph. Historically, it served as the city's main artery, known as the Qasaba, and housed many souqs (markets) and monumental buildings commissioned by rulers and elites. The street is renowned for its dense collection of historic Islamic architecture, particularly in the Bayn al-Qasrayn area, which features significant monuments of Islamic Cairo.
