Bayn al-Qasrayn (Arabic: بين القصرين, lit. 'between the two palaces') is an area located along al-Mu'izz Street in the center of medieval Islamic Cairo, within present day Cairo, Egypt. It corresponds to what was formerly a plaza between two palace complexes constructed in the 10th century by the Fatimids, as part of their palace-city named al-Qahirah (now Cairo). This later became the site of many monumental buildings constructed during the Ayyubid, Mamluk, and Ottoman periods, up to the 19th century. Many of these historical monuments are still standing today.
