In West Pomerania, Poland, stands a rather odd grove of pine trees. Some 400 of the trees have taken the peculiar shapes you see pictured, while the surrounding forest is filled with pines that have grown the ordinary way, true and straight.
The trees, collectively called “The Crooked Forest,” were estimated to have been planted from 1930 to 1934, when Pomerania was still a German possession. And while nature-driven theories have been put forth as to why the trees are shaped this way—some think heavy snowfall caused the bends when the trees were sapling-aged—what seems more likely is that this is man-made intervention.
The prevailing theory is that the trees were deliberately shaped, when seven to ten years old, for the purpose of eventually harvesting the naturally bent wood to construct something. Boats, furniture or some type of structure are the best guesses. On the nautical side, IFLScience’sJustine Alford dug up this quote from a Navy & Marine article on 19th Century shipbuilding called “Wooden Vessel Ship Construction:”
Oaks from the areas of Northern Europe were fine for the development of long straight planking, but the gnarled English “Hedgerow” Oak was the best for the natural curved timbers used to strengthen the ship internally. Trees were even deliberately bent in certain ways so as to ‘grow’ a needed set of curved timbers. These curved timbers were known as ‘compass’ timbers.
