The city was named al-Mu'izziyya al-Qahira, the "Victorious City of al-Mu'izz", later simply called "al-Qahira", which gave us the modern name of Cairo.[1]: 80 The new city was located northeast of Fustat, the previous capital and main city of Egypt. Jawhar organized the city so that the caliphal palace complex was at its center, in addition to the main mosque, al-Azhar, to the southeast. The palace complex consisted of two main parts: the Great Eastern Palace, the first to be laid out in 970 by Jawhar for the arrival of the triumphant Caliph al-Mu'izz, and the Western Palace, which was added under his successor, Caliph al-'Aziz (r. 975–996).[1]: 96 Together they served as the residences of the caliphs and their family throughout the Fatimid period, and were thus also known as the Dar al-Khilafa ("Abode of the Caliphate").[2] Information about the layout and appearance of these palaces comes from a few written reports, and especially from the chronicles of the Arab historian Maqrizi and of the Persian traveler Nasir Khusraw.[2]
