During the time Jerusalem was in Crusader hands, the mosque was used as a royal palace and commonly known as Solomon's Temple, despite not being the real one. In 1119, it was transformed into a headquarters for a newly established Crusader order founded by its Grand Master Hugues de Payens, whose name derived from that location: Poor Fellow-Soldiers of Christ and of the Temple of Solomon, or shortly known as the Knights Templar.
Behind the scenes
Aqsa is Arabic word meaning "remote, (very) far, distant"; Al-Aqsa is traditionally translated as "the farthest".
The mosque is depicted as being smaller than in reality and some of its details and structure are different compared to the real one.
