Goethe Oak

Perhaps the most famous one is the oak tree near Weimar, Germany, on the Ettersberg, at the foot of which was the castle of Charlotte von Stein.

[1] The oak, in the middle of a beech forest, is named thus because it is supposedly the tree under which Goethe wrote "Wanderer's Nightsong",[2] or, alternatively, the location where he composed the Walpurgisnacht passages of his Faust.

[1] It is preserved (being cast in concrete under the auspices of the DDR government, which also laid a plaque saying "Goethe Eiche"[5]) and is part of the Buchenwald memorial.

[10] In Der Totenwald, camp survivor Ernst Wiechert recalls standing under the oak and reflecting on the two Germanies it represented—what later scholars would call the "Januskopf Deutschlands", the Weimar-Buchenwald dichotomy.

[13] The Arnsberg Forest Nature Park in Sauerland claims one as well (a beech named for Friedrich Schiller fell victim to a storm in 2007[14]).
