The Crooked Forest (Polish: Krzywy Las), is a grove of oddly-shaped pine trees located outside Nowe Czarnowo, West Pomerania, Poland.
This grove of approximately 100 pines was planted around 1930, when its location was still within the German province of Pomerania. Each pine tree bends sharply to the North just above ground level, then curves back upright after a sideways excursion of three to nine feet (1–3 m). It is generally believed that some form of human tool or technique was used to make the trees grow this way, but the method and motive are not currently known. It has been speculated that the trees may have been deformed to create naturally curved timber for use in furniture or boat building. Others surmise that a snowstorm could have knocked the trees like this, but to date nobody knows what really happened to these pine trees.
