A wall inscription found in the Christian Quarter of Jerusalem. During the First Crusade in 1099, Christian armies had captured Jerusalem from Muslim control. After this, it became dangerous for Christian groups to pilgrimage to the Holy Land, having to cross through Muslim-controlled territories. Around 1118, a French knight named Hugues de Payens, created a military order along with a small group of friends and family, forming the start of the Knights Templar.

Inside the Mysterious Sites Where the Knights Templar Gathered in Secret
Known for their austere code of conduct and signature style of dress, the Knights Templar was a large organization of devout Christians throughout Western Europe. Their mission? To protect European travelers visiting the Holy Land. As the organization flourished, it turned into a wealthy and powerful military order. Some believe the mysterious Templars went underground and still exist today.

The underground caverns were filled with rubble, but once the sites were excavated the structures were discovered and amazingly remained intact. (Dan Rosen/Alamy Stock Photo)
