The Templum Domini was a Christian church set up on the site of the Dome of the Rock during the Crusades.
During the Crusades the Dome of the Rock was given to the Augustinians, who turned it into a church while the Al-Aqsa Mosque became a royal stable. The Knights Templar, who believed the Dome of the Rock was the site of the Temple of Solomon, later set up their headquarters in the Al-Aqsa Mosque adjacent to the Dome for much of the 12th century. The "Templum Domini", as they called it, was featured on the official seals of the Order's Grand Masters (such as Everard des Barres and Renaud de Vichiers), and it became the architectural model for Templar churches across Europe. One of these typically Templar churches was the old Saint Michael church (until the 15th century) in Roeselare which is located on the extension of the orthodromic distance line from the Dome of the Rock to the Kokino observatory.
