Paris, October 2010. Inside a 19th century covered market in the heart of Paris, an extraordinary archaeological excavation was carried out in the place where the Knights Templar built a place to house their treasures in the 13th century on their return from Jerusalem. Added to the information, of great historical importance, obtained from the excavation, are new archives located by Vatican historians, which will reveal previously unknown information about the Knights Templar and their participation in the Crusades.
