English: Al-Muizz li-Din Allah al-Fatimi Street (Arabic: شارع المعز لدين الله الفاطمي‎), or al-Muizz street for short, is a major north-to-south street in the walled city of historic Cairo, Egypt. It is one of Cairo's oldest streets as it dates back to the foundation of the city (not counting the earlier Fustat) by the Fatimid dynasty in the 10th century, under their fourth caliph, Al-Mu'izz li-Din Allah (after whom the street is named).[1] Historically, it was the most important artery of the city and was often referred to as the Qasaba (or Qasabah). It constituted the main axis of the city's economic zones where its souqs (markets) were concentrated.[1] The street's prestige also attracted the construction of many monumental religious and charitable buildings commissioned by Egypt's rulers and elites, making it a dense repository of historic Islamic architecture in Cairo.[2][1] This is especially evident in the Bayn al-Qasrayn area, which is lined with some of the most important monuments of Islamic Cairo.
