On internet much information on the Knights Templar (Templiers) in France is available. Many mix fact and imagination, myths and truths. Two sites are above question.
Project Beauceant (www.templiers.org) is an extensive website (in French), with the main objective to set up a kind of encyclopedia on the Templar Order and a catalogue of diverse historical remnants that the presence of these men has left everywhere in Europe and the Middle-East. To do it, the Project is open to any person, professional or not, who wants to share his research and experiences on this topic. It also contains much information on Templar
commanderies. Regretfully many commanderies in the Centre of France seem to be missing. For these other sources have to be considered, such as the ones below.
Templiers.net is another great website (in French) with a lot of information on the Knights Templar and the crusades. It includes very detailed descriptions of the French
commanderies, in alphabetical order and per Département.
Mainly from this latter source TemplarsNow composed a new map containing all known and probable Templar sites in the Allier department according to
templiers.net. To this were added sites mentioned on
templarii3m.free.fr. All sites were checked on other maps and aerial photographs and categorized, and indicated on the best possible geographical location.
The resulting map is shown below and can also be reached by
this link. The work on the map continues, adding information from other sources. TemplarsNow acknowledges gratefully that this map could not have been made without the data from
templiers.net.
Similar maps for (for now) 20 other French Departements can be found
here.
