This stand of bent pine trees known as the Crooked Forest is easily one of the strangest places in Central Europe. Located outside of Nowe Czarnowo, West Pomerania, Poland, the nearly 400 trees are widely agreed to have been shaped by human hands sometime in the 1930s, but for what purposes is still up for debate.

Each tree is bent near the base at 90 degrees, a form that could possibly be helpful in boat or furniture making. Strangely enough, every tree is bent in exactly the same direction: due North. A quick search online reveals a host of conspiracy theories ranging from witchcraft to energy fields.

Whatever the reason, we’re glad photographer Kilian Schönberger (previously) stopped by to capture these photos. You can see more from the series on Behance.
