During the Silesian foresters' congress in 1895, 3 oaks were planted near the former forester's lodge of the Przyborów Forest District: Katarzyna, Matylda and Mikołaj. "Katarzyna" commemorated Katharina Emma Jenny Helena von Reichenbach-Goschuetz, (1861-1941) the second wife of Karol Ludwik Erdmann Ferdinand V, Prince of Siedlisko and Bytom. "Matylda" commemorated Matylda Gruchwitz-Lilliendahl (1825-1909), wife of Aleksander Gruchwitz - a famous factory owner from Nowa Sól. The person of Matylda Gruschwitz is associated with the large-scale, famous donations of the Gruschwitz family for social purposes. "Nicholas" was dedicated to Nikolaus Prince von Handjery (1836-1900), doctor of law, president of Legnica until 1894, whom the German emperor entrusted with delivering congratulations on the occasion of the 150th anniversary of the founding of Nowa Sól. Currently, only two are still standing. Due to the risk of falling onto the roadway, it was necessary to cut down one of them.
