Cedar is the national tree of Lebanon. It appears on the flag and the coat of arms of the country. Lebanese Cedar (Cedrus libani) has been known since ancient times as the best building material, especially for ships. All the cultures that changed in the area of today's Lebanon left a trace of the use of the Lebanese Cedar for various purposes. There are specimens of this tree that are believed to be about 1500 years old in Cedars Of God Bsharri. Right next to Kadisha Valley, monks from the valley venerated the Cedars Of God forest. Today, it is guarded by the state, and with good reason. These slow-growing silent giants have helped create a good part of human history.
