On 23 June 2003 in the park at Pöls, a giant spruce (or grand fir) was uprooted, which in 1856 by King I. Otto of Greece (cousin of Emperor Franz Joseph I of Austria - the father of Otto I and the mother of Francis Joseph Were siblings and brother-in-law of Marie Friederike von Washington), was planted together with his wife Amalie (duchess of Oldenburg and sister of Friederike von Washington), on the occasion of his visit to Pöls Castle, and had a height of 5 meters (H. Rößmann - quoted from the Upper Bavarian Archive, Volume 131).
