Germany had a swastika of trees not found for 60 years

de bene esse: literally, of well-being, morally acceptable but subject to future validation or exception

 In a pine forest near Zernikow in Uckermark district, Brandenburg in Northeastern Germany, a patch of larch trees covering 3,600 sqm or 4,300 sq yd. were carefully arranged to look like a swastika.

 

While it is unclear how the patch came to be, it has been suggested it was planted in 1937 by locals to prove their loyalty after a local shop owner was denounced and sent to a concentration camp for listening to the BBC. Another theory is that the Hitler Youth planted it.

For a few weeks each year during autumn and spring, the color of the larch leaves change, causing a contrast with the deep green of the pine forest. The short duration of this color change and scarcity of private airplanes meant that the swastika patch went undiscovered until 1992, and not fully removed until 2000!
