The Crooked Forest, known in Polish as Krzywy Las, sits near the town of Gryfino in western Poland. It holds roughly 400 pine trees whose trunks bend sharply at the base before curving back upward. The trees were planted in the 1930s, and the cause of the distinctive curvature remains unexplained.
Nobody knows why, but I can imidiately see what happened. This is simply somebody who chopped down some trees, planted new ones, let them grow a couple meters, then chopping off all the branches except those pointing southeast.
