In 2013, the oak growing in the park was declared a state-protected natural heritage asset (Rokiškis d.). The size of its mighty trunk is 6.3 m, diameter – 2 m, and height – 30.5 m.
According to the owner of the Ilzenberg Manor Vaidas Barakauskas, the oak for a long time had been hiding among other trees, however, once they started trimming of the restored Manor Park, the oak became a celebrity of the park right away. Ilzenberg Manor park is state-protected since 1963, covers an area of 10 ha, and more than 23 species of trees are growing in it.

“The Ilzenberg Oak Manor is a natural botanical heritage asset. To declare a site as protected, it must meet the criteria established: to have large enough dimensions. Its aesthetic value, suitability to adapt it to visits, to the development of natural sciences, education, the possibility to add the site to the tourist route are the issues of high importance. The Ilzenberg oak has met all of these the listed requirements and was declared the state-protected natural heritage asset,” says G.Mikalauskas.
