The Crooked Forest is a grove of oddly-shaped pine trees located near the town of Gryfino, West Pomerania, Poland.
This grove of 400 pines was planted in the village of Nowe Czarnowo in around 1930. 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 or bend this way, but the method was never determined and remains a mystery to this day. 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 bent the trunks, however, there is little evidence of that and nobody knows what happened to the pine trees. Some hypothesize that a unique gravitational pull in this particular area caused the trees to grow curved northwards, but this theory does not hold up to basic scientific scrutiny given that gravity pulls things downward and not at a curve. The site is open to the public and serves as a notable tourist attraction in the region.
