Vertical presents the biggest known to me oak of the Bialowieza National Park, which has a record in trunk's perimeter at the height of 130cm(counting from its base-725cm) and a record in total height(41m). This height record is shared together with an oak growing near so-called 'Detour'. It is a huge tree with a very wide-stretching crown. The trunk's height up to the first branch is about 17-18m, and the total trunk's height is 26-27m.
