Al-Aqsa Mosque located in Jerusalem, in present-day Israel, is one of the most important Muslim temples in the world. The sacred object stands on the Temple Mount and is considered the third holiest site of Islam, second only to Mecca and Medina. Al-Aqsa Mosque was built along with the Dome of the Rock in the period of 660–691 AD
Both the Al-Aqsa Mosque and the Dome of the Rock, which is also a holy place of Muslims, are souvenirs of the prophet Muhammad's night trip to Jerusalem. The architectural appearance of the mosque refers to the Roman style, which is why some scholars suggest that it was originally the church of St. Mary. Al-Aqsa can hold up to 30,000 faithful.
During periodic renovations, various ruling dynasties of the Islamic caliphate added new elements to the mosque and its precincts. Additions such as the dome, facade, minbar, minarets and internal structure were built. When the Crusaders captured Jerusalem in 1099, they used the mosque as a palace and the Dome of the Rock as a church. The mosque's original purpose was restored after it was recovered by Saladin in 1187.
