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.
Square du Temple
The Knights Templar actually began in the 12th century, constructing a fort first (Vieux Temple or Old Temple) in Le Marais. In the 13th century, a new fortress was built as their European headquarters. The enclosure, called "enclos du Temple", originally featured a number of buildings important to the running of the Order, and included a church and a massive turreted keep known as "Grosse Tour" (great tower), and a smaller tower called "Tour de César" (Caesar's Tower).
