Al-Aqsa or al-Masjid al-Aqṣā is the compound of Islamic religious buildings that sit atop the Temple Mount, also known as the Haram al-Sharif, in the Old City of Jerusalem, including the Dome of the Rock, many mosques and prayer halls, madrasas, zawiyas, khalwas and other domes and religious structures, as well as the four encircling minarets. It is considered the third holiest site in Islam. The compound's main congregational mosque or prayer hall is variously known as Al-Aqsa Mosque, Qibli Mosque or al-Jāmiʿ al-Aqṣā, while in some sources it is also known as al-Masjid al-Aqṣā; the wider compound is sometimes known as Al-Aqsa Mosque compound in order to avoid confusion.
