Forest swastika - a gigantic Nazi swastika made of larch trees

The forest swastika was a patch of larch trees covering 3,600 m2 (4,300 sq yd) area of pine forest near Zernikow, Uckermark district, Brandenburg, in northeastern Germany, carefully arranged to look like a swastika. It was probably planted near the height of Hitler's power, in the 1930s.

It is unclear why the trees were planted and arranged thus. It has been suggested that it was laid out in 1937 by locals to prove their loyalty after a businessman in the area was denounced and sent to a concentration camp by the Nazi Party for listening to the BBC. Another theory is that a zealous forester convinced local Hitler Youth members to plant the trees in commemoration of Adolf Hitler's birthday. One source maintains it was planted by a warden, either out of support for the Hitler regime, or due to an order from state officials.

For a few weeks every year in the autumn and in the spring, the colour of the larch leaves would change, contrasting with the deep green of the pine forest. The short duration of the effect combined with the fact that the image could only be discerned from the air and the relative scarcity of privately owned aeroplanes in the area meant that the swastika went largely unnoticed after the fall of the Nazi Party. During the subsequent Communist period, Communist authorities reportedly knew of its existence but made no effort to remove it. However, in 1992, the reunified German government ordered aerial surveys of all state-owned land. The photographs were examined by forestry students, who immediately noticed the design.

The Brandenburg state authorities, concerned about damage to the region's image and the possibility that the area would become a pilgrimage site for Nazi supporters, attempted to destroy the design by removing 43 of the 100 larch trees in 1995. However, the figure remained discernible with the remaining 57 trees as well as some tree which had regrown, and in 2000 German tabloids published further aerial photographs showing the prominence of the swastika. By this time, ownership of around half the land on which the trees sat had been sold into private hands, but permission was gained to fell a further 25 trees on the government-owned area on December 1, 2000, and the image was largely obscured.
