Knights Templar in England
An inventory by Geoffrey Fitz Stephen reveals that by 1185, the Order of the Knights Templar had extensive holdings in London, Hertfordshire, Essex, Kent, Warwickshire, Worcestershire, Salop, Oxfordshire, Cornwall, Lincolnshire and Yorkshire. The involvement of Templars in financial matters is highlighted by Walter of Coventry's story of Gilbert de Ogrestan, the Knight Templar accused of embezzling taxes collected in the Saladin tithe of 1188. He was severely punished by his contemporary Master.
Temple Church
After the capture of Jerusalem in 1099 by the Crusaders, the Dome of the Rock was given to the Augustinians, who turned it into a church (while the Al-Aqsa Mosque became a royal palace). Because the Dome of the Rock was the site of the Temple of Solomon, the Knights Templar 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 the Dome of the Rock, featured on the official seals of the Order's Grand Masters (such as Everard des Barres and Renaud de Vichiers), and along with the Church of the Holy Sepulchre upon which it was based soon became the architectural model for Round Templar churches across Europe.
