The Tree of Crows (also known as Raven Tree) is an oil painting of 1822 by the German Romantic artist Caspar David Friedrich. Acquired by the Musée du Louvre in 1975, it has been called one of Friedrich's "most compelling paintings."The painting depicts a twisted oak tree, bare but for a few dead leaves, seen against an evening sky. An inscription on the back of the canvas refers to the hill at the painting's center as a Hünengrab, or dolmen, a prehistoric burial ground.
