The Kadisha Valley is near the Forest of the Cedars of God, survivors of the ancient Cedars of Lebanon, the most highly prized building materials of the ancient world. The forest is said to contain 375 individual trees, two claimed to be over 3,000 years old, ten over 1,000 years old, and the remainder at least centuries old. The Lebanon Cedar (Cedrus Libani) is described in ancient works on botany as the oldest tree in the world.
