The Great Oak

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.
